Matt Riedemann 7661995b69 Enable cross-cell resize in the nova-multi-cell job
This changes the nova-multi-cell job to essentially
force cross-cell resize and cold migration. By "force"
I mean there is only one compute in each cell and
resize to the same host is disabled, so the scheduler
has no option but to move the server to the other cell.

This adds a new role to write the nova policy.yaml file
to enable cross-cell resize and a pre-run playbook so
that the policy file setup before tempest runs.

Setup multi-cell policy on the controller host. This should not require a restart of the n-api service (the policy changes should be read dynamically). The stack user must exist on the controller host first.
