This change removes the loop watching for "/var/lock/subsys/lxc" from
the lxc-container module. This change simply runs the command within
a container using the lxc CLI tools which should be responcible for
locking and unlocking on their own.

The lxc container restart state does not ensure that the container
is in fact started unless another config or command is passed into
the task. to fix this the module simply needs to have the function
call added ``self._container_startup()`` after the container is
put into a stopped state.

The clone state was removed in favor of making the module more
declarative. This change was done in response to review in PR #328
from @bcoca.
In the commit new examples were created on how this feature works.
This commit adds the overlayfs type to the lxc_container module. In
Adding the overlayfs type the commit adds the ability to clone a
container. While cloning is not locked down to only the overlayfs
container backend it is of particular interest when using the overlayfs
backend as it provides for amazingly fast snapshots.
Changes to the resource types and documentation have been added on how
the new backend type can be used along with the clone operation.
This PR addresses a question asked on the original merged pull request
for overlayfs support which came from @fghaas on PR
"https://github.com/ansible/ansible-modules-extras/pull/123".
The overlayfs archive function is a first class function and will
allow for the containers to be backed-up using all methods which
brings support up to that of all other storage backends.
The option parsing object within the module was performing a split
on an '=' sign and assuming that there would only ever be one '='
in a user provided option. Sadly, the assumption is incorrect and
the list comprehension that is building the options list needs to
be set to split on the first occurrence of an '=' sign in a given
option string. This commit adds the required change to make it
possible for options to contain additional '=' signs and be handled
correctly.
The volume create methods were making an assumption on the unit
sizes being presented by the `vgdisplay` and the `lvdisplay`
commands. To correct the assumption the commands will now enforce
a unit size of "g" which will alway convert sives to gigabytes.
This was an issue brought up by @hughsaunders.
The new module will allow users to control LXC containers from ansible.
The module was built for use in LXC >= 1.0 or greater and implements most
of what can be done using the various lxc clients with regards to running
containers. This first module is geared only at managing lxc containers.
The module provides:
build containers
destroy containers
archive containers
info from a single container
start / stop / restart containers
run commands within containers
add/modify lxc config for a container
supports backends including LVM
