For principal - subordinate plugin type relations where the
principal Python payload imports code from packages managed by a
subordinate, upgrades can be problematic.
This change will allow a subordinate charm that have opted into the
feature to inform its principal about all implemented release -
packages combinations ahead of time. With this information in place
the principal can do the upgrade in one operation without risk of
charm relation RPC type processing at a critical moment.
