cluster leader changed mid-sync

[Alvaro Uria]

Ubuntu Xenial, OpenStack Charms 17.02.

swift-proxy/0 as juju leader, while s-p/{1,13} as non juju leaders.

Juju leader goes into error state because it claims that the cluster leader has changed mid-sync:

Workaround:
1) stop the leader (jujud-unit-swift-proxy-0)
2) wait until the leader moves to a different unit (ie. to swift-proxy/1)
3) start jujud-unit-swift-proxy-0

As a collateral issue, swift-proxy/0 juju unit stopped swift-proxy service. Such unit had the VIP.

As this is over a year old, and lots of changes have been made, I'm setting to incomplete to see if it's still an issue. If not, then it will expire.
