Code Issues Proposed changes

change the nova cache to dogpile.cache.memcached 

Currently there are issues with using the memcache_pool backend as
the memcache driver for nova under python3[0][1] which doesnt seem
like they have a quick fix or something that is backportable to
rocky

This moves the default cache from oslo_cache.memcache_pool to
dogpile.cache.memcached so we can move forward with python3
enabled images.

memcache backend for nova has been changed from oslo_cache.memcache_pool
to dogpile.cache.memcached. You can revert to previous behaviour by
setting conf.nova.cache.backend to "oslo_cache.memcache_pool".
