Code Issues Proposed changes

glance help <subcommand>: Clearly specify which options are mandatory 

Earlier glance help <subcommand> was listing required arguments as
optional arguments in help text. Added new argument group to list
required argument properly.

$ glance help stores-delete

Example before this change:
usage: glance stores-delete --store <STORE_ID> <IMAGE_ID>

Delete image from specific store.

Positional arguments:
  <IMAGE_ID>          ID of image to update.

Optional arguments:
  --store <STORE_ID>  Store to delete image from.

After this change:
usage: glance stores-delete --store <STORE_ID> <IMAGE_ID>

Delete image from specific store.

Positional arguments:
  <IMAGE_ID>          ID of image to update.

Required arguments:
  --store <STORE_ID>  Store to delete image from.
