These updates, on the master branch, are to support testing the caracal
packages and support of the charms for caracal. They do NOT lock the charms
down, and don't change the testing branches to stable branches.
Tests sporadically fail the live-migration portion when the compute
nodes have different processor families. Set the cpu-mode and cpu-model
to the lowest denominator in the CI to prevent this.
The API service needs to listen on all IP addresses to allow different
haproxy frontends reach it out.
By default the service binds to 127.0.0.1, and binding it to
options.service_listen_info.watcher_api.ip prevents the assess_status()
code to succeed, this is a common pattern[0]
This change expands the testing bundles to deploy a fully functional
cloud and run the testing class WatcherTests which uses the
vm_workload_consolidation strategy[0].
