This commit was bulk generated and pushed by the OpenDev sysadmins

Attempts have been made to correct repository namespaces and
hostnames based on simple pattern matching, but it's possible some
were updated incorrectly or missed entirely. Please reach out to us
via the contact information listed at https://opendev.org/ with any
questions you may have.
There may be situations where leader-elected hook is executed without
being the leader and making leader_set() calls fail, this patch verifies
if it's the leader before attempting to use leader_set()

(cherry picked from commit 1219f7b2a213af5d5697a1c4cb48486e9c08c81e)
The percona-cluster charm was rendering, and therefore, restarting
after each peer joined. This causes race conditions with the leader
handing out client credentials.
This is due to the parallel but conflicting goals of building the
cluster as quickly as possible but also delaying client relations until
the full cluster is completely ready.
The charm relied on the bootstrap_uuid being set among peers. However,
the bootstrap_uuid is set intentionally early in pursuit of the first
goal building the cluster quickly. It did not signify true readiness.
This change adds another peer relation setting, "ready", that each node
sets when it has bootstrapped, its hacluster is complete, and it has a
sufficient number of peers.
The cluster is considered ready when (min-cluster-size) peers have
indicated readiness. This fulfils goal number two delaying client
relations until the full cluster is ready.
