**NB**: This PR should be considered controversial because it restarts the
password server after each keepalived transition, rather than stopping the
service on transitions to backup or fault states.
This decision was taken in anticipation of CLOUDSTACK-9035, which suggests
that the password server should be running on backup redundant routers.
However, this may be ill-advised.
I'm happy to incorporate any feedback into this PR.
