Args:
operation_id: An object identifying the operation.
group: The group identifier of the operation.
method: The method identifier of the operation.
subscription: A base.Subscription describing the customer's interest in the
results of the operation.
timeout: A length of time in seconds to allow for the operation.
initial_metadata: An initial metadata value to be sent to the other side of
the operation. May be None if the initial metadata will be passed later or
if there will be no initial metadata passed at all.
payload: The first payload value to be transmitted to the other side. May be
None if there is no such value or if the customer chose not to pass it at
operation invocation.
completion: A base.Completion value indicating the end of values passed to
the other side of the operation.
ticket_sink: A callable that accepts links.Tickets and delivers them to the
other side of the operation.
termination_action: A callable that accepts the outcome of the operation as
a base.Outcome value to be called on operation completion.
pool: A thread pool with which to do the work of the operation.
