  This command can fail for the following reasons:
  * The Membership specified does not exist.
  * The user does not have access to the Membership specified.
  * The caller did not specify the location (--location) if referring to
  location other than global.

  ## EXAMPLES

  The following command lists Bindings in global Membership `MEMBERSHIP_NAME`:

    $ {command} --membership=MEMBERSHIP_NAME

  To list all the bindings associated with regional membership
  `MEMBERSHIP_NAME`, provide the location LOCATION_NAME for the Membership where
  the Binding belongs along with membership name.

  $ {command} --membership=MEMBERSHIP_NAME --location=LOCATION_NAME
