Moving the CLI to python allows for easier
maintenance and larger feature-set.

This patch introduces a few breaking changes!
The changes stem the nature of the cliff package.
- the order of parameters must be
  kolla-ansible <action> <arguments>
- mariadb_backup and mariadb_recovery now are
  mariadb-backup and mariadb-recovery

Partially-Implements: blueprint python-package

This adds a new test script for the new python based build script. A new
tox target has been created to execute it for usage in the gate.
Eventually, the other build script stuff can be deleted, but that won't
be done until full functionality exists in the new build.py.

Paritally-Implements: blueprint build-script

Add set_configs function that implements the flow from the proposed
ansible-multi spec. Move start.sh to config-internal.sh to preserve existing
behaviour.

config-externall.sh copies the appropriate configs in from the bind'd
location and sets permissions and ownership appropriately.

Partially Implements: blueprint ansible-multi
