Updates an Endpoint with a long running operation.

// It will require modifications to work:

@param endpoint Required. The Endpoint which replaces the resource on the server. Currently we
    only support updating the `client_connection_config` field, all the other fields' update
    will be blocked.
@throws com.google.api.gax.rpc.ApiException if the remote call fails
