If this field is provided, then the Endpoint's
[traffic_split][google.cloud.aiplatform.v1.Endpoint.traffic_split] will be
overwritten with it. If last DeployedModel is being undeployed from the
Endpoint, the [Endpoint.traffic_split] will always end up empty when this
call returns. A DeployedModel will be successfully undeployed only if it
doesn't have any traffic assigned to it when this method executes, or if
this field unassigns any traffic to it.
