Support for specifying custom RBD striping parameters

I suspect some workloads would benefit from a smaller object size. Suse currently recommends an object size of 1MB for VMware workloads in their Ceph iSCSI documentation.

Is this feasible to expose these knobs via the API, or are there other additional considerations required in other parts of the IO pipeline here?

You can create images via the rbd CLI with whatever parameters you'd like and then use the gwcli to just attach a pre-existing image as a new LUN.
