Removed entitites

[ltrilety]

Entities removed from gluster stay in tendrl and are shown in Graphite metrics and so in Grafana too.

Example of reproduction scenario:

1. Create new volume
2. Wait till the volume with proper bricks is present in Tendrl/Grafana
3. Remove the volume
4. Wait a while

Volume and its bricks remain in tendrl.
However bricks still "exist" on gluster machines no new data is collected.

@rishubhjain @shtripat Is this issue taken care of in the latest release ? If yes Pls update the issue

[shtripat]

@rishubhjain I feel with recent changes to update dashboard based on create/delete events from gluster for volumes/bricks, this should be taken care. Kindly confirm.

@shtripat @nnDarshan The update dashboard is updating alert dashboard and not the normal dashboards, The issue I feel is regarding the normal dashboard, In my opinion this issue should not reappear but I am testing it to be sure. will update the issue once testing is done

@ltrilety When volumes is deleted volume details from grafana and graphite immediately, and from etcd volume, details are deleted by ttl.

Issue is fixed, please verify
