1. librbd: make group and group snapshot IDs more random …

   Image IDs suffered from the same issue -- it was addressed in commit
   be83736 ("librbd: block_name_prefix is not created randomly").
   The code for generating group IDs is duplicated in api/Group.cc and
   got missed.
   
   Instead of cut-and-pasting the fix, just call generate_image_id()
   directly and rename variables for more explicitness.
   
   Before:
   
     $ rados -p rbd ls | grep rbd_group_header
     rbd_group_header.10256b8b4567
     rbd_group_header.10216b8b4567
     rbd_group_header.10236b8b4567
     rbd_group_header.101f6b8b4567
   
   After:
   
     $ rados -p rbd ls | grep rbd_group_header
     rbd_group_header.10255f555a5
     rbd_group_header.1023f347eafb
     rbd_group_header.101f24c75111
