Changes the intended size of the managed instance group. If you increase the
size, the group creates new instances using the current instance template. If
you decrease the size, the group deletes one or more instances.

The resize operation is marked DONE if the resize request is successful. The
underlying actions take additional time. You must separately verify the
status of the creating or deleting actions 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.
(regionInstanceGroupManagers.resize)

@param string $project Project ID for this request.
@param string $region Name of the region scoping this request.
@param string $instanceGroupManager Name of the managed instance group.
@param int $size Number of instances that should exist in this instance group
manager.
@param array $optParams Optional parameters.

@opt_param string requestId 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).
