Bugzilla: 1497120

From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>

Add two statuses for use when the 'pause-before-switchover'
capability is enabled.

'pre-switchover' is the state that we wait in for management
to allow us to continue.
'device' is the state we enter while serialising the devices
after management gives us the OK.
