Description

This is primarily a refactoring.

The prototype for modifying the registry is currently:

Try<bool> operator () (
    Registry* registry,
    hashset<SlaveID>* slaveIDs,
    bool strict);

In order to support Maintenance schedules (possibly Quotas as well), there should be an alternate prototype for Maintenance. Something like:

Try<bool> operation () (
    Maintenance* maintenance,
    bool strict);

The existing RegistrarProcess::update (src/master/registrar.cpp) should be refactored to allow for more than one key. If necessary, refactor existing operations defined in src/master/master.hpp (AdminSlave, ReadminSlave, RemoveSlave).
