We need to add support for -S|--select for all commands where possible, mainly the ones which suggest --select use if multiple VGs are found with the same name.

For example, lvcreate is one of them:

[root@rhel6-a ~]# vgs -o+vg_uuid -S vg_name=vg
  VG   #PV #LV #SN Attr   VSize VFree VG UUID                               
  vg     1   1   0 wz--n- 4.00g 3.99g eHZp2F-7Qdk-p6br-Z8cI-iEwi-LWIl-ScaCr4
  vg     1   1   0 wz--n- 4.00g 3.99g GhDzAe-LAav-yhCu-WF4e-G1zn-FtrQ-yh15OP

[root@rhel6-a ~]# lvcreate -l1 vg
  Multiple VGs found with the same name: skipping vg
  Use the VG UUID with --select vg_uuid=<uuid>

[root@rhel6-a ~]# lvcreate -l1 -S vg_uuid=eHZp2F-7Qdk-p6br-Z8cI-iEwi-LWIl-ScaCr4
lvcreate: invalid option -- 'S'
  Error during parsing of command line.

However, in such cases, we need to make sure that the --select returns only one item that should be processed (one VG for the lvcreate example above). If the result of selection is a set which contains more items, we need to error out and suggest users to refine their selection so there's only one item coming as a result of the selection.

We should either fix this for 6.8 or we need to remove the "Use the VG UUID with --select vg_uuid=<uuid>" message for commands where --select is not yet supported.
