DPE-2288 - feat: support rollbacks, add statuses #81

Changes Made

`feat: support managed rollback after failed upgrade`

Units now stay in the same state they were before failing, not also failing
Running pre-upgrade-check action after a cluster has failed sets state=recovering to the leader
upgrade-charm modifies upgrade-stack to insert any units that were already popped + completed (i.e not the failed ones)
- Failed units are inserted to the top of the existing stack
upgrade-granted now only emitted when all units are ready

`feat: add unit statuses during upgrade`

BlockedStatus with optional cause passed by set_unit_failed() if unit fails during
BlockedStatus with generic message if any other unit failed during
MaintenanceStatus throughout
ActiveStatus when setting back to state=idle
