we should clone freezer code before run bootstray,
otherwise, the directory /opt/stack/freezer which is empty will
mount into freezer_api container.

Closes-Bug: #1888242

Change-Id: I7c22dd380fd5b1dff7b421109c4ae37bab11834a

This change defaults freezer to use mariadb as default backend for database
and adds elasticsearch as an optional backend due to the requirement of
freezer to use elasticsearch version 2.3.0. The default elasticsearch in
kolla-ansible is 5.6.x and that doesn't work with freezer.

Added needed options to the elasticsearch backend like:
 - protocol
 - address
 - port
 - number of replicas

Add a possibility to mount sources as volumes to containers,
in "more than documentation" way. That will let us to use kolla
as a replacement for devstack.
