(fix) Check sync of only active rack controllers
- The import resources job waits for rack controllers to sync the imported resources. In an environment that rack pods have been scheduled away from a node, it leaves a dead rack controller in the MAAS database. We cannot gate on dead controllers syncing as rackd is no longer running, so now only look at rack controllers with a running rackd. Change-Id: I5ca16a0c97ed201a08844ca7c82c2cbb7d059aa7
