Sync c-h for py38 support and add focal to metadata

Browse Source 
Note that this is NOT the focal testing enablement for the charm.  This
is a sync of charm-helpers and a add of 'focal' to the metadata to
enable testing, and landing, of other charms' focal functional testing
enablement.  focal testing will be added soon.
