Module for managing nodes in a Rackspace Cloud Load Balancer
MySQL variables module
mysql_replication module added
use lgetfilecon_raw instead of lgetfilecon to not depend on local level translation

If SELinux is enabled and mcstrans is running, daemons are restarted on each
run. After further debugging, it turn out that ansible compare the untranslated
level 's0' with the translated level 'SystemLow' due to mcstrans being running,
which trigger a handler since this is considered as a change.
Enhancements to provide pool creation and attributes

Fix typo: alises -> aliases
Fix to better handle concurrent runs of module against same pool
Ensure plugin_loader.all() only loads one instance

by ensuring all basedirs, plugin paths and extra
paths are handled as absolute paths and are checked
to not add any doubles.

This fixes the corner case where e.g. the user has
an additional plugin path configured to a dir
relative to his playbooks or inventory location,
which also matches the  _plugin subdir relative to
one of the basedirs in the play.

For most plugins this doesn't show as an obvious issue
except for callback_plugins, which might fire more
than once. Other plugins (inventory and template
plugins) might unnecessarily be ran twice.

e.g. ansible.cfg has
callback_plugins   = ./plays/callback_plugins
and plays/ contains a playbook file:
.
├── ansible.cfg
├── inventory
└── plays
    ├── callback_plugins
    │   └── timestamp.py
    └── site.yml
