Also added this feature to the CHANGELOG

This patch also checks specifically for a return code of 255, which
indicates an unknown SSH error of some kind. When that happens, ansible
will now recommend running with -vvvv (if not enabled) or show the
output from 'ssh -vvv' (when it is enabled)

DEFAULT_MODULE_PATH in setup.py

Typo fix from `accelerated: true` to `accelerate: true`

This shouldn't generally be needed unless you're working in an environment
that uses rediculously long FQDNs; if the name is too long, you wind up
hitting unix domain socket filepath limits enforced by ssh.

Merge branch 'fix/apt_repository_update_cache' of https://github.com/resmo/ansible into resmo-fix/apt_repository_update_cache

The default behavior is to update_cache if changed.

If you add more then one repo, you may not want to update cache for every repo separately.
So you can now disable update_cache with this new option e.g. update_cache=no

Updating cache can also be handled using the apt module.

Cosmetic - Digital ocean cleanup

The EXAMPLES block here has two copies of the same docs,
one nicely formatted, the other less so.

It looks like a pass was made to clean up the docs but the old
cruftier ones were never removed.

zabbix inventory: print errors to stderr

Two fixes:

* parameter name is selevel, not serange.
* Fix split on selinux context to limit to max of 4 since the selevel
  may contain ':' characters.  This was fixed in
  selinux_default_context() and selinux_context().

apt: fixed duplicate fail_json

use DEFAULT_MODULE_PATH in setup.py so that there is a chance to override with ANSIBLE_LIBRARY env variable

Fixed monit restarted error.

Errors everytime...

Previously, includes had to receive variables via a special 'vars'
field. With this patch, the include syntax becomes a more natural
datastructure without special fields and is more akin to the way
role includes/dependencies work.

Tested with the following playbook:
---
- hosts: localhost
  connection: local
  tasks:
  - { include: inc1.yml, a: 1 }
  - include: inc2.yml
    b: 2
  - include: inc3.yml
    with_items:
    - x
    - y
    - z
