Description

Original discussion
Currently, there is no easy way to test how JM failover (revoke and grant leadership) affects other features with the MiniCluster and its testing resource rule. The custom HA services can be provided to the TestingMiniCluster but there is no simple HA services to support revoking and granting leadership with a valid in-memory checkpoint store. Providing a way to enable such embedded HA services for the MiniCluster out of the box allows to implement IT cases similar to E2E tests.
