-- Flags the specified instances to be immediately removed from the managed
-- instance group. Abandoning an instance does not delete the instance, but
-- it does remove the instance from any target pools that are applied by
-- the managed instance group. This method reduces the targetSize of the
-- managed instance group by the number of instances that you abandon. This
-- operation is marked as DONE when the action is scheduled even if the
-- instances have not yet been removed from the group. You must separately
-- verify the status of the abandoning action with the listmanagedinstances
-- method. If the group is part of a backend service that has enabled
-- connection draining, it can take up to 60 seconds after the connection
-- draining duration has elapsed before the VM instance is removed or
-- deleted. You can specify a maximum of 1000 instances with this method
-- per request.

-- | An optional request ID to identify requests. Specify a unique request ID
-- so that if you must retry your request, the server will know to ignore
-- the request if it has already been completed. For example, consider a
-- situation where you make an initial request and the request times out.
-- If you make the request again with the same request ID, the server can
-- check if original operation with the same request ID was received, and
-- if so, will ignore the second request. This prevents clients from
-- accidentally creating duplicate commitments. The request ID must be a
-- valid UUID with the exception that zero UUID is not supported
-- (00000000-0000-0000-0000-000000000000).
