Become plugins (#50991)
* [WIP] become plugins

Move from hardcoded method to plugins for ease of use, expansion and overrides
  - load into connection as it is going to be the main consumer
  - play_context will also use to keep backwards compat API
  - ensure shell is used to construct commands when needed
  - migrate settings remove from base config in favor of plugin specific configs
  - cleanup ansible-doc
  - add become plugin docs
  - remove deprecated sudo/su code and keywords
  - adjust become options for cli
  - set plugin options from context
  - ensure config defs are avaialbe before instance
  - refactored getting the shell plugin, fixed tests
     - changed into regex as they were string matching, which does not work with random string generation
     - explicitly set flags for play context tests
 - moved plugin loading up front
 - now loads for basedir also
 - allow pyc/o for non m modules
 - fixes to tests and some plugins
 - migrate to play objects fro play_context
 - simiplify gathering
 -  added utf8 headers
 - moved option setting
 - add fail msg to dzdo
 - use tuple for multiple options on fail/missing
 - fix relative plugin paths
 - shift from play context to play
 - all tasks already inherit this from play directly
 - remove obsolete 'set play'
 - correct environment handling
 - add wrap_exe option to pfexec
 - fix runas to noop
 - fixed setting play context
 - added password configs
 - removed required false
 - remove from doc building till they are ready

future development:
  - deal with 'enable' and 'runas' which are not 'command wrappers' but 'state flags' and currently hardcoded in diff subsystems

* cleanup

  remove callers to removed func
  removed --sudo cli doc refs
  remove runas become_exe
  ensure keyerorr on plugin
  also fix backwards compat, missing method is attributeerror, not ansible error
  get remote_user consistently
  ignore missing system_tmpdirs on plugin load
  correct config precedence
  add deprecation
  fix networking imports
  backwards compat for plugins using BECOME_METHODS

* Port become_plugins to context.CLIARGS

This is a work in progress:
* Stop passing options around everywhere as we can use context.CLIARGS
  instead

* Refactor make_become_commands as asked for by alikins

* Typo in comment fix

* Stop loading values from the cli in more than one place

Both play and play_context were saving default values from the cli
arguments directly.  This changes things so that the default values are
loaded into the play and then play_context takes them from there.

* Rename BECOME_PLUGIN_PATH to DEFAULT_BECOME_PLUGIN_PATH

As alikins said, all other plugin paths are named
DEFAULT_plugintype_PLUGIN_PATH.  If we're going to rename these, that
should be done all at one time rather than piecemeal.

* One to throw away

This is a set of hacks to get setting FieldAttribute defaults to command
line args to work.  It's not fully done yet.

After talking it over with sivel and jimi-c this should be done by
fixing FieldAttributeBase and _get_parent_attribute() calls to do the
right thing when there is a non-None default.

What we want to be able to do ideally is something like this:

class Base(FieldAttributeBase):
    _check_mode = FieldAttribute([..] default=lambda: context.CLIARGS['check'])

class Play(Base):
    # lambda so that we have a chance to parse the command line args
    # before we get here.  In the future we might be able to restructure
    # this so that the cli parsing code runs before these classes are
    # defined.

class Task(Base):
    pass

And still have a playbook like this function:

---
- hosts:
  tasks:
  - command: whoami
    check_mode: True

(The check_mode test that is added as a separate commit in this PR will
let you test variations on this case).

There's a few separate reasons that the code doesn't let us do this or
a non-ugly workaround for this as written right now.  The fix that
jimi-c, sivel, and I talked about may let us do this or it may still
require a workaround (but less ugly) (having one class that has the
FieldAttributes with default values and one class that inherits from
that but just overrides the FieldAttributes which now have defaults)

* Revert "One to throw away"

This reverts commit 23aa883cbed11429ef1be2a2d0ed18f83a3b8064.

* Set FieldAttr defaults directly from CLIARGS

* Remove dead code

* Move timeout directly to PlayContext, it's never needed on Play

* just for backwards compat, add a static version of BECOME_METHODS to constants

* Make the become attr on the connection public, since it's used outside of the connection

* Logic fix

* Nuke connection testing if it supports specific become methods

* Remove unused vars

* Address rebase issues

* Remove unused import

* Various cleanups

* Restore network_cli check in _low_level_execute_command

* Doc updates

* Various additional minor cleanups

* Add auth_timeout parameter when supported

Paramiko 2.2 introduces the auth_timeout parameter. This will set the
parameter to the same value of the timeout parameter to prevent
"Authentication timeout" errors.

* Conditionally add auth_timeout to ssh.connect

Renamed sock_kwarg to ssh_connect_kwargs and conditionally added the
auth_timeout parameter based on the installed paramiko version.

Reboot - Fix errors when using Paramiko connection (#49002)
Different connection plugins return different data when throwing exceptions. The Paramiko connection plugin does not return a text sting, which caused an exception.

The ssh connection plugin returns multi-line errors, which makes the debug logs harder to read. Only return the last line in that case in order to make the logs more readable.

When experiencing a connection failure, reset the connection.

Add reset() to paramiko_ssh

Indicate thet conection state is False when running close(). This is needed by the ensure_connected() decorator to work properly.

Dag Wieers 1afbe29642 Remove transport_test for some connection types (#28450)
So we are removing the transport_test for the listed connection types,
because they fail to take into account bastion or proxy servers for
testing the transport.

The result of removing this, is that modules using this facility will do
a complete round-trip attempt, running a module, which is a bit heavier but correct.

This fixes #23774

Dag Wieers 52959ebdc1 wait_for_connection: Wait for system to become reachable (#20011)
* WIP: wait_for_connection: Wait for system to be reachable

This action plugin allows to check when a system is back online and
usable by Ansible.

As an example, when doing a SysPrep and running Enable-WinRM.ps1, it
takes between 10 to 20 seconds between the WinRM TCP port to open, and
it actually being able to server Ansible requests. This time is variable
and depends on the boot process.

Current implementation is specific for Windows (WinRM) only, this will
be fixed shortly.

This fixes #19998

* Support other transport types

* Various improvements

- Fix reported typo
- Add transport_test support in accelerate plugin
- Ensure port is an integer

* Improve examples

* Small fixes

- Use correct ConfigureRemotingForAnsible.ps1 script name
- Only use win_ping when remote shell is known to be Powershell
- Add integration tests to CI framework

Peter Sprygada 9aa8547016 adds two new plugins that use ansible-connection for persistence (#18572)
* adds new connection plugin `network_cli` which builds on paramiko
* adds new plugin `terminal` used for manipulating network_cli terminals
* adds new field to play_context `network_os` settable as ansible_network_os

This commit adds the plugins necesary to establish a persistent cli connection
to network devices of ssh.  It builds on the paramiko connection plugin
to create a shell environment that will persistent through ansible-connection.
The `newtork_cli` plugin then uses the network_os in the instance of
PlayContext to load the appropriate network OS environment plugin for
handling opening and closing of shells as well as privilege escalation.

Peter Sprygada 7df5a0abd0 adds config option to auto add keys when using paramiko (#18598)
* updates paramiko_ssh to auto add keys
* updates constants with new config options

This commit adds a new feature that will allow paramiko to automatically
accept and save a host ssh key.  This feature is controlled by the
`host_key_auto_add` config setting in the paramiko section.  The default
is False to maintain current functionality.  It also includes a new
setting `look_for_keys` with the default to False for maintaining current the
current setting.
