  CLOUDSTACK-8302 - Cleanup snapshot on KVM with RBD Snapshot removing implemented on RBD.
1. On management side: when created new shanpshot we checking if our primary storage is RBD,
then do not remove record from cloud.snapshot_store_ref with link to Ceph image via 'install_path'
field. 2. On management side: when removing snapshot, also send command to agent 'DeleteCommand'.
3. On agent side: method implemented 'public Answer deleteSnapshot(final DeleteCommand cmd)'

> I just build a lab with CloudStack 4.4.2 + CentOS 6.6 KVM + Ceph/RBD 0.80.8.
> I deploy an instance on RBD and I create the ROOT volume snapshots. When delete a snapshot
the UI show OK, but the snapshot of the volume in the RBD pool is still exist.
> And I find the code in com/cloud/hypervisor/kvm/storage/KVMStorageProcessor.java: 
> …
>     @Override
>     public Answer deleteSnapshot(DeleteCommand cmd) {
>         return new Answer(cmd);
>     }
> …
> deleteSnapshot() does not be implememented. And I also find the code:
> ...
>     @Override
>     public Answer createTemplateFromSnapshot(CopyCommand cmd) {
>         return null;  //To change body of implemented methods use File | Settings | File
Templates.
>     }
> ...
> So does createTenokateFromSnapshot(). I just look for it in MASTER branch but not do
that yet. Will CloudStack Dev Team plan to do that ? Thanks .
