Review request for mesos, Adam B, Andrew Schwartzmeyer, Daniel Pravat, Greg Mann, John Kordich,
Joseph Wu, and Vinod Kone.


Bugs: MESOS-6803
    https://issues.apache.org/jira/browse/MESOS-6803


Repository: mesos


Description
-------

Currently, when `HAS_AUTHENTICATION` is undefined, the Agent will
use `delay` to schedule a random time in the future to register with the
Master, to avoid the thundering herd problem after a Master failover.
The authentication codepath, in contrast, schedules the registration
immediately.

In tests where we have `Clock::pause`'d when we are supposed to be
registering the slave, the authention codepath will succeeed, while
no-authentication codepath will hang forever.

A much more detailed analysis of this situation exists in MESOS-6803.

This commit will resolve this issue for `slave_tests.cpp` by changing
the tests to not use `Clock::pause` when we are waiting for Agent
registration.

Testing
-------

Added `delay` to the call to `authenticate` in `Slave::detected`, ran tests to find failing
tests in `SlaveTest.*`, then fixed, then ran again.


Thanks,

Alex Clemmer
