cont.

So I added the config manually to the leader:

juju run -u rabbitmq-server/0 -- leader-set cluster-partition-handling=ignore

# leader-get again
juju run -u rabbitmq-server/0 -- leader-get
__leader_get_migrated_settings__: '["octavia.passwd", "glance.passwd", "neutron.passwd",
  "cinder.passwd", "ceilometer.passwd", "nova.passwd"]'
ceilometer.passwd: zZpPS8j9Xt8ScT5nCHMJkkx8prVxBZJwrmpBNTmjV3x96PYcMpTSbgydG9jncYpZ
