Matt Riedemann 9b21d1067a Block swap volume on volumes with >1 rw attachment ... If we're swapping from a multiattach volume that has more than one read/write attachment, another server on the secondary attachment could be writing to the volume which is not getting copied into the volume to which we're swapping, so we could have data loss during the swap. This change does volume read/write attachment counting for the volume we're swapping from and if there is more than one read/write attachment on the volume, the swap volume operation fails with a 400 BadRequest error.
