journal: pass groupUUID to be used for omap name reserve

Browse Source 
This commit adds groupUUID param for `ReserveName` to be used for
OMAP name reserve instead of auto-generating.
This is useful for mirroring and metro-DR ensuring that mirrored
resources have consistent OMAP names across mirrored clusters.
