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

Documentation fixes and enhancements
Automatically prepend partition if non-fully qualified monitors are passed
Fix: with_items and complex_args
fix
Exit with status 3 if no failures but unreachable.

Provide hints to playbook callers that a playbook execution had
unreachable vs failures. 2 == failures, 3 == no failures, but
unreachable hosts. 0 continues to be all good.
quantum_network should not default network provider type to local

It should allow the Quantum service to decide based on its configuration.

Allow to use '*test*' in enablerepo for yum action

Yum commandline permit to use a wildcard to enable and disable
repositories in the --enablerepo switch, permitting to enable
a complete set of repository at once ( like all rpmfusion, all
update-testing, etc ).

However, this doesn't work in yum due to more stringent checks
that verify that a exact match is given for the name of the
repository , see commit 5c26805.

This commit enhance the check by permitting to test more than
1 repository at a time, thus permitting to use wildcards.

Enforce alphanumeric ordering for plugins grabbed via glob.

If this isn't done, it's left to directory ordering which can result
in indeterminent behaviour.
