Review request for mesos, Andy Konwinski, Charles Reiss, Matei Zaharia, John Sirois, and Vinod


Apologies for a rather large diff. I meant to do a few independent changes but they all got
mangled into one because of subtle dependencies between them.

* Changed MesosSchedulerDriver to take a FrameworkInfo instead of a
  name and possibly FrameworkID. This required adding an optional
  FrameworkID to FrameworkInfo. The hope is that with this change can
  more easily update the FrameworkInfo semantics without requiring
  recompilation. For example, as we add better support for auth
  entication we should hopefully be able to do that directly in
  FrameworkInfo. We also simplified the C++ MesosSchedulerDriver by
  removing unused constructors (that also don't have versions in
  either Java or Python).

* Renamed the 'url' parameter of MesosSchedulerDriver to 'master' and
  updated the allowable schemes of 'master' to include a host:port
  pair (we internally add 'mas ter@') and replaced zoo:// with zk://
  and zoofile:// with file:// (but with different semantics, see the
  documentation). We also changed the master webui to show t he
  host:port and removed the PID and updated and added tests related to
  creating MasterDetectors from the above schemes.

* Replaced the --url argument of mesos-master with --zk argument for

* Removed 'code' from the Scheduler/Executor::error callback since it
  was not being used (nor did it seem useful in the future).

* Made some naming consistency changes across the C++, Java, and
  Python interfaces (sched -> scheduler, exec -> executor, etc).
