NFS/GlusterFS: Skip incorrectly formatted shares

Shares should always be of the form address:/volume.  If they are
not (i.e., are missing the '/'), then skip them and issue a warning
message.  This will prevent us from sending incorrect connection_info
dicts to Nova.

Multipathing during copy image to volume and copy volume to image
operations doesn't work properly if there are different targets
associated with different portals for a mulitpath device.
