The related bug indicated that the Fernet keys could get out of sync between the leader and non-leader units. This patchset assumes that hooks fail, or that units are off-line when the rotation occurs. Thus it tries hard to ensure that the keys are in sync. It still uses juju to 'send' the keys from the leader to the subordinate units, so in that sense, it is not a fix to the related bug, but it does make it more robust.
