forked from rook/rook
adding fields `TotalBytes`, `UsedBytes`, `AvailableBytes`
`LastUpdated` to the ceph cluster CR's status section to
report the storage details of ceph cluster.
`TotalBytes`: Total storage capacity in bytes
`UsedBytes`: Total storage used in bytes
`AvailableBytes`: Total storage used in bytes(Total - Used)
`LastUpdated`: Last update time
for example(I have added 10GB disk):
`kubectl get cephclusters.ceph.rook.io -o yaml`
```
status:
ceph:
capacity:
bytesAvailable: 9657188352
bytesTotal: 10733223936
bytesUsed: 1076035584
lastUpdated: "2020-10-23T12:57:48Z"
```
