Default to creating agent token for each entity

Currently, we require the operator to specify an existing agent token
to use for all entities.  This means the operator needs to make a call
to MaaS to determine the agent token ID before being able to deploy the
environment.  This change creates a new agent token w/ label matching
the entity in question and configures the agent to use that token.  If
the user variable maas_agent_token is defined, then we skip creating an
agent token and use the token specified.

Flip flopped all of the git repos

On all of our projects were were depending on git.openstack.org to be
always available and the definitive source for all of our git repos.
Sadly git.openstack.org has frequent timeouts and has proven itself to
be unpredictable. To aid in deployments and ensure better overall
deployment performance all of the project git repos have been flip
flipped. Now github.com/openstack will be used for all clone operations
as the primary git repository and if there are issues with github we will
fall back to git.openstack.org.

Adds a simple to use and cron script for python packages

This script is intended as a simple method for croning the
creation of python wheels.

updated wheel builder python app

This commit increases performance when building all of the python packages
that our systems depended on. This also provides the system a capability
to build specific versions of packages that may be required and or duplicated
throughout the various projects.

IE a particular project may require a specific version of a package to be
installed that may be a lower revision that what is already built.

The cpu_allocation_ratio and disk_allocation_ratio settings were added
previously, but do not take effect unless the matching filters are
applied.

I think the time unit was supposed to be in seconds. If omitted, the default time unit is miliseconds, which I don't think was intended.
Idempotency for LXC cloning

Previously, clone operations where the new container already exists were
reporting as failed. This commit modifies that behavior so that if the
new container exists, it returns the facts for that container instead of
failing.

To facilitate these changes, a _container_exists method was added which
returns True or False based on whether or not the container name is in
the output from self._list().

I also made a few fixes in the documentation by removing trailing spaces
and fixing a typo in the state on line 222.
