Alembic allows us to change in future DB schema, which we are going to do soon. This patch adds under rally/common/db/sqlalchemy/migrations required files for alembic as well as a first init migrations that was autogenerated from models that we have. As well this patch adds CLI commands for DB management Change-Id: I7caa090aa5c4c6563b7e34d0d09baa039a3aa718 Co-Authored-By: Illia Khudoshyn <ikhudoshyn@mirantis.com>
