Re: [I] Middle-Managers disappearing from the cluster (druid)

   Looks like the issue happens, because peon unannounces the middlemanager it runs on when it terminates and removes `druidDiscoveryAnnouncement-cluster-identifier` and `druidDiscoveryAnnouncement-id-hash` labels.
   
    Labels with no peons:
   ```yaml
   druidDiscoveryAnnouncement-cluster-identifier: dev
   druidDiscoveryAnnouncement-id-hash: "1276105065"
   druidDiscoveryAnnouncement-middleManager: "true"
   ```
   
   Labels with peon:
   ```yaml
   druidDiscoveryAnnouncement-cluster-identifier: dev
   druidDiscoveryAnnouncement-id-hash: "1276108075"
   druidDiscoveryAnnouncement-middleManager: "true"
   druidDiscoveryAnnouncement-peon: "true"
   ```
   
   Labels after peon finishes:
   ```yaml
   druidDiscoveryAnnouncement-middleManager: "true"
   ```
