Doug Szumski 952b53089b Copy Nova role as a basis for the Nova cell role
The idea is to factor out a role for deploying Nova related services
to cells. Since all deployments use cells, this role can be used
in both regular deployments which have just cell0 and cell1,
and deployments with many cells.

Partially Implements: blueprint support-nova-cells

# there would be a way to check whether all nova services are using the latest
# version, but currently there is not. Instead, wait a short time for all nova
# compute services to update the version of their service in the database.
# This seems to take around 10 seconds, but the default is 30 to allow room

# NOTE(mgoddard): Currently (just prior to Stein release), sending SIGHUP to
# nova compute services leaves them in a broken state in which they cannot
# start new instances. The following error is seen in the logs:
# "In shutdown, no new events can be scheduled"
# To work around this we restart the nova-compute services.
# Speaking to the nova team, this seems to be an issue in oslo.service,
# with a fix proposed here: https://review.openstack.org/#/c/641907.
# This issue also seems to affect the proxy services, which exit non-zero in
# reponse to a SIGHUP, so restart those too.
# The issue actually affects all nova services, since they remain with RPC
# version pinned to the previous release:
# https://bugs.launchpad.net/kolla-ansible/+bug/1833069.
# TODO(mgoddard): Use SIGHUP when this bug has been fixed.
