Issue MESOS-4951: Enable actors to pass an authentication realm to libprocess
To prepare for MESOS-4902, the Mesos master and agent need a way to pass the desired authentication realm to libprocess. Since some endpoints (like {{/profiler/*}}) get installed in libprocess, the master/agent should be able to specify during initialization what authentication realm the libprocess-level endpoints will be authenticated under.
