This extension was added less than 6 month ago, and so cannot be used on a release
older than Grizzly ( like Folsom ).

Commit of the extension : https://review.openstack.org/#/c/21453/

See https://wiki.openstack.org/wiki/ReleaseNotes/Grizzly#Key_New_Features_2

Previous patch was reverted due to the fact that there was an issue
with the results not always being a dictionary (they're sometimes
a unicode string, ie. when the with_items is used with yum). This
minor change corrects that by checking for a dict object.

This reverts commit 1a4e6e41.

docfix: grammar in docstring for sysctl module

that loop over a lookup plugin. Fixes #3704 and #3735

to ensure consistent behavior, hosts should look like this:

    hosts: webservers:&boston:!rack42

So when applying the host selectors, run those without the "&" first,
then the &s, then the !s.

Closes #3500

apt: Run remove commands noninteractively

Update callbacks used for async tasks

Minor doc update to s3 & ec2 modules

Add support for INI comments that begin with '#' or ';'

changed role path template to read all vars instead of just extra_vars

Proper packaging support for RHEL/CentOS 5 

S3folder

adding param to the ec2_vol module allowing custom iops setting when creating EBS volume

Correctly check for failed status from an async task.  Use runner_on_async_failed callback (instead of runner_on_failed) when an async task times out.  Add runner_on_async_ok callback when a task is started in fire and forget mode.

Adds some additional docs about the module parameters for s3
and ec2 modules.

Ini file format does not have a standard but ';' is used more often than '#' for comments

Update supervisorctl

Fixed the example.

I'm seeing ansible hang when trying to remove a package, and the hung
process is `whiptail` like in #2763. It looks like we only use
`APT_ENVVARS` and `DPKG_OPTIONS` for the `apt` commands in install()
and upgrade(). This change uses them in remove() as well, which fixes
the hang.

and the _meta hash contains a "hostvars", don't call --host hostname for any elements
and just serve them directly for performance enhancements with the external inventory
script and a large number of hosts.

Add urpmi as a package manager for mandriva-based distribution

Added support of an optional init method for action modules like rsync that need to alter the connection and other inject data before it's established.
