This PR adds the option to retry failed ssh executions, if the failure
is caused by ssh itself, not the remote command. This can be helpful if
there are transient network issues. Retries are only implemented in the
openssh connection plugin and are disabled by default. Retries are
enabled by setting ssh_connection > retries to an integer greater
than 0.
Running a long series of playbooks, or a short playbook against a large
cluster may result in transient ssh failures, some examples logged
[here](https://trello.com/c/1yh6csEQ/13-ssh-errors).
Ansible should be able to retry an ssh connection in order to survive
transient failures.
Ansible marks a host as failed the first time it fails to contact it.
The --force-handlers command line argument was not correctly running
handlers on hosts which had tasks that later failed. This corrects that,
and also allows you to specify force_handlers in ansible.cfg or in a
play.

Adds new settings for managing retry files:
* retry_files_enabled, defaults to True
* retry_files_save_path, defaults to ~/.ansible-retry
This change was adapted from PR #5515.
Generate warnings when users are shelling out to commands
rather than using modules
Can be turned off on a per-action line with the documented
warn=False flag. Can be turned off globally using
command_warnings = False in ansible config file.
Print out warnings using the standard playbook callbacks.
Created some additional tests in TestRunner.test_command
and also a demonstration playbook.
