Remove outstanding_requests_ from QuotaDispatcherHost and associated
subclasses to address TODO. These subclasses existed to carry the
request_id around. Now that the request_id has been removed from the
QuotaDispatcherHost system, these subclasses are no longer needed.

Also change the design of QuotaDispatcherHost slightly; instead of
creating a separate object to hold all the request parameters, curry
the parameters into the various async callbacks.
