Given that pymysql is pure python and has no C binding
dependencies, we no longer need the role to install the
MariaDB client libraries.

In order to reduce the packages required to pip install on to the hosts,
we allow the service setup to be delegated to a specific host, defaulting
to the deploy host. We also switch as many tasks as possible to using the
built-in Ansible modules which make use of the shade library.
The 'virtualenv' package is now installed appropriately by the openstack_hosts
role, so there's no need to install it any more. The 'httplib2' package is a
legacy Ansible requirement for the get_url/get_uri module which is no longer
needed. The keystone client library is not required any more now that we're
using the upstream modules. As there are no required packages left, the task
to install them is also removed.

With addition of pip_install on every node, we don't
need to have pip_install as a meta dependency.

We need to add openstack ansible information in the role
metadata to be able to track role maturity. With it,
we can create a role maturity table and take decisions about
role deprecations.

The update of the apt cache and the package installation
can all be handled in a single task by providing the
package action plugin with the right parameters. This
removes an extra task to optimise execution.
The minimum Ansible version is raised to 2.2 due to a
known bug [1] in Ansible's apt module which does not
update the cache properly if the cache update and the
install are combined in a single task.

Starting in Ansible 2.0, the get_url [1] module provides the
ability for a checksum to be provided to the get_url module
which will be verified against the local destination file
and the task skipped if it matches.

This patch implements the use of this functionality.
The ability to ignore a venv download failure is also removed
as this is not necessary or desirable. It is better for the
download to fail and the playbook execution to stop immediately
so that the failure point is exposed.
