New metric about snapshots

[dstubq]

If possible i would like to see the following metrics:

vm_vmware_snapshots (with total snapshots for a vm)
vmware_vm_snapshot_timestamp_seconds (unix timestamp of a snapshot)

This would be nice feature to have so that we can use prometheus alertmanager to alert for old snapshots , or too many snapshots for a vm.

Much appreciated
