Bug description:
  Context:
  *  openstack HA deployment using 1504 charms release
  * 'mysql' juju service deployed using percona-cluster charm r57
  * 'cinder' service deployed using cinder charm r91
  * staged deployment as:

  #1 deploy cinder num_units:3, mysql num_units:2
   (among others), with their hacluster relations
  #2 relate all OS services (ie cinder<->mysql, etc)
  #3 add 3rd unit to mysql

  FYI using mojo with
  lp:~jjo/openstack-mojo-specs/mojo-openstack-specs-add-mojo-bootstack-specs :
  - specs/bootstack/ha_phased/icehouse/manifest
  - specs/bootstack/ha_phased/icehouse/bootstack-example.yaml

  Issue:
  * after #3, cinder/0 fails with
  "CRITICAL cinder [-] OperationalError: (OperationalError) (1045, "Access denied for user 'cinder'@'172.20.0.184' (using password: YES)") None None"
  - http://paste.ubuntu.com/10928144/

  * cinder/0 (172.20.0.184) has a different password at mysql/0 than the rest:
  - http://paste.ubuntu.com/10928182/

  * cinder/0 shows different relation data against mysql/0,1 (/2 didn't finish deploying)
  - http://paste.ubuntu.com/10928280/

  * cinder/1,2 are stuck re-running shared-db-relation-changed hook
  (more than ~1d already), FYI number of this hook's lines at log:
  $ for i in cinder/{0..2};do juju ssh $i 'sudo grep -cH shared-db-relation-changed /var/log/juju/unit-cinder-?.log';done
