[libvirt] [PATCHv2 2/3] qemu: conf: Parse RBD storage pool from domain xml

[Adam Walters]

Modify switch statement in qemuTranslateDiskSourcePool
to parse the storage pool definition for RBD pools
instead of throwing an error. I do throw errors for
any other usage case of VIR_STORAGE_VOL_NETWORK, as my
code does not cover their use cases currently. Once I
have the ability to test such usage cases, I will
revisit those possibilities.
