@param vmwareEngineNetwork Required. VMware Engine network description.
@param updateMask Required. Field mask is used to specify the fields to be overwritten in the
    VMware Engine network resource by the update. The fields specified in the `update_mask` are
    relative to the resource, not the full request. A field will be overwritten if it is in the
    mask. If the user does not provide a mask then all fields will be overwritten. Only the
    following fields can be updated: `description`.
@throws com.google.api.gax.rpc.ApiException if the remote call fails
