on relation departed, ceph-client flags aren't cleared

[Adam Dyess]

Removing the ceph-mon application completely from a model and removing all ceph-client relations from a model, kubernetes-control-plane still sees all the flags regarding that relation active -- the worst ones are :

❯ juju run -a kubernetes-control-plane charms.reactive get_flags | egrep 'ceph.pool|ceph-client.'
    ceph-client.available
    ceph-client.connected
    ceph-client.pools.available
    endpoint.ceph-client.changed
    endpoint.ceph-client.changed.auth
    ...
    endpoint.ceph-client.departed

The kubernetes-control-plane charm would handle some of these if the .connected and .available flags were cleared, but they aren't
