Updates charm upgrades to use channels, tracks, and risks instead
of URLs.
Currently these tests only upgrade OpenStack charms and packages.
The OVN, ceph, and misc charms and payloads are not upgraded.
Remove instance creation since tempest can be used to verify the
cloud.
* Set timeout on juju_wait()
* Remove leftover traces
Traces should be made with logging.debug(). These traces
are probably leftovers from the development phase.
These are additions to make the Octavia Upgrade tests in the
charmed-openstack-tests repository a little easier to specify. Also
depends on the zaza change [1].

This patch modifies the existing openstack upgrade tests so that they
work with focal (by explicitly supporting mysql-innodb-cluster), and are
also interruptable and resumable (at a charm level). It also makes them
work with the udpated 'get_upgrade_groups()' that ultimately gets a List
of Tuples rather than a dictionary.
