<pre>
Required. Field mask is used to specify the fields to be overwritten in the
IndexEndpoint resource by the update.
The fields specified in the update_mask are relative to the resource, not
the full request.
A field of the resource will be overwritten if it is in the mask.
Empty field mask is not allowed.
If the mask is "*", then this is a full replacement of the resource.
