Fixes #7307

This is a useful example to help debug how facts and vars are being collated.

* Added capability to support multiple keys, so clients from different
  machines can connect to a single daemon instance
* Any activity on the daemon will cause the timeout to extend, so that the
  daemon must be idle for the full number of minutes before it will auto-
  shutdown
* Various other small fixes to remove some redundancy

Fixes #5171

This fixes an issue related to the new run_command changes, whereby
Popen fails to run a command when an executable is specified + shell=False
and there are multiple positional arguments (see Popen docs for details)

Fixes #6047

Add the start of an integration test structure using Ansible playbooks, also added an assert action plugin to make writing those easier.

Fixes #5812

The timeout is in seconds (int), and the extra quote at the end could throw someone off if they're copying and pasting the example.

The example for the fail module doesn't work:
  http://www.ansibleworks.com/docs/modules.html#fail

The current text shows:
    - fail: msg="The system may not be provisioned according to the CMDB status."
      when: "{{ cmdb_status }} != 'to-be-staged'"

The "when" documentation indicates that the argument is already a Jinja2
expression:
  http://www.ansibleworks.com/docs/playbooks_conditionals.html#the-when-statement

Thus, the following is
      when: cmdb_status != "to-be-staged"

is preferred even though the following could work but generates a
deprecation warning:
      when: {{cmdb_status != "to-be-staged"}}

Adds a new option to wait_for to wait for a file to exist on the file
system before continuing, optionally takes a search_regex param to match
text in the file.

is a class method. Pyflakes complained about it.

- explictely import json, since this is used ( only to silence pyflakes)
- remove shutil as it is unused

Fixes #4485 add an ipv6 parameter to accelerate so that the daemon will bind to an ipv6 port instead of ipv4

Make it slightly more clear what side of the connection is missing keyczar if using accelerate mode.

on EL5. Fix #4763

unsupported string prefix in 2.4

http://docs.python.org/release/2.4/ref/strings.html
This is also ignored on later version of python 2
and is present only for python 3 conversion, as seen
on http://docs.python.org/2/reference/lexical_analysis.html#string-literals

Fix https://github.com/ansible/ansible/issues/4739

This setting makes the timeout for each play configurable, rather than
hard-coding it at 300 seconds (now the default if left unspecified)

Fixes #4162

Commands will now be started up in a separate task from the main
handler thread, so that it can be monitored for completeness while
sending a keepalive packet back to the controller to avoid a socket
receive timeout.
