  """Delete a Membership Binding.

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

  ## EXAMPLES

  To delete Membership Binding `BINDING_NAME` in global Membership
  `MEMBERSHIP_NAME` for a global membership:

    $ {command} BINDING_NAME --membership=MEMBERSHIP_NAME

  To delete a Binding `BINDING_NAME` associated with regional membership
  `MEMBERSHIP_NAME`, provide the location LOCATION_NAME for the Membership where
  the Binding belongs along with the membership name.

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