As recently there was back-and-forth with this hardcoded value
(0.001 -> 0.01 -> 0.005), obviousely the optimal value for it depends on
Ansible usage scanario and is better to be configurable.
This patch adds a new config option in DEFAULT section,
`internal_poll_interval`, with default of 0.001 corresponding to the
value hardcoded in Ansible v2.1.
This config option is then used instead of hardcoded values where
needed.

We couldn't copy to_unicode, to_bytes, to_str into module_utils because
of licensing. So once created it we had two sets of functions that did
the same things but had different implementations. To remedy that, this
change removes the ansible.utils.unicode versions of those functions.
This feature also cleans up and extends the meta subsystem:
* Allows for some meta actions (noop, clear_facts, clear_host_errors,
and end_play) to operate on a per-host basis, meaning they can work
with the free strategy as expected.
* Allows for conditionals on meta tasks.
* Fixes a bug where (for the linear strategy) metas were not treated
as a run_once task, meaning every host in inventory would run the
meta task.
Fixes#1476
In the free strategy, we mark a host as blocked when it has work to do
(the PlayIterator returns a task) to prevent multiple tasks from being sent
to the host. However, we check for role duplicates after setting the blocked
flag, but were not clearing that when the task was skipped leading to an
infinite loop. This patch corrects that by clearing the blocked flag when
the task is skipped.
Fixes#15681
* Don't filter hosts remaining based on their failed state. Instead rely
on the PlayIterator to return None/ITERATING_COMPLETE when the host is
failed.
* In the free strategy, make sure we wait outside the host loop for all
pending results to be processed.
* Use the internal _set_failed_state() instead of manually setting things
when a failed child state is hit
Fixes#15623
* Make sure dep chains are checked recursively for nested blocks
* Fixing iterator is_failed() check to make sure we're not in a
rescue block before returning True
* Use is_failed() to test whether a host should be added to the TQM
failed_hosts list
* Use is_failed() when compiling the list of hosts left to iterate
over in both the linear and free strategies
Fixes#14222
* Raise an error if the action is using BYPASS_HOST_LOOP, to prevent
unexpected behavior from those actions
* Show a warning regarding tasks marked as run_once, as the free strategy
does not yet support that behavior
* Minor tweak to linear strategies run_once code to make sure we don't
raise an error if an action isn't found
* Fixed a bug in PlayIterator when ITERATING_ALWAYS, where the block
was advanced but the incorrect data structure elements were cleared
* Cleaned up the logic of is_failed() in PlayIterator
* Fixed a bug in the free strategy which had not been updated to use
the base strategy _execute_meta() method
* Stopped strategies from using is_failed() to determine if tasks should
still be fetched for a host
Fixes#14040
* Added additional methods to the iterator code to assess host failures
while also taking into account the block rescue/always states
* Fixed bugs in the free strategy, where results were not always being
processed after being collected
* Added some prettier printing to the state output from iterator
Fixes#13699
Also fixes a bug where we were passing an incorrect number of parameters to
_do_handler_run() when processing an include file in a handler task/block.
Fixes#13560
The comment was taken literally from lib/plugins/strategy/linear.py and
makes no sense in free.py where we have no noop tasks.
Also update the debug messages.
Previously, we were filtering the task list on tags for each host
that was including the file, based on the idea that the variables
had to include the host information. However, the top level task
filtering is play-context only, which should also apply to the
included tasks. Tags cannot and should not be based on hostvars.
