Merge lp:~mterry/snappy/rollback-reboot-15.04 into lp:~snappy-dev/snappy/15.04-deprecated

When rolling back. output version info, especially any messages about rebooting to pick up the new version.

This is a backport of r485 from trunk.

This makes "rollback" work just like "update" which makes the same output about parts it updates.

I didn't add a test. Seems like such cmd tests tend to go in the selftests branch.
