Dmitriy Rabotyagov 0a24c61e3e Improve way of cache backend selection
At the moment we don't provide any option rather then use memcached
backend. With that we also hardocde list of packages that should be
installed inside virtualenv for selected backend.

Adding bmemcached requirement to oslo_cache.memcache_pool [1] gives us
opportunity to refactor this bit of deployment and allow to be more
flexible in backend selection and requirements installation for it.

New variables have been added to manage used cache backends:
* ``openstack_cache_backend``: defines driver, that will be used for
caching.
Default: oslo_cache.memcache_pool
* ``openstack_cache_backend_map``: maps selected backend to
the oslo driver that should be installed and configured for it.
