[Feature] Multi ceph cluster support

[letonphat1988]

Hi swiftgist,
I carefuly read you documents but I'm being confused about how to define the ceph cluster name that named with another name not like "ceph" ?
example:

"pool": "rbd",
"cluster":'CEPH_01"

I think this is a healpful feature that can help we have multi CEPH Cluster backend.

Hello letonphat1988,
If you need to target a different cluster, would the --ceph option work? That is, specify the ceph configuration file of the other cluster.
If you do need to use different keys, the -n name option has been recently merged and may prove useful. If you are trying to use one iSCSI gateway to manage images from two different Ceph clusters, that is out of the capability of lrbd currently.
