Review request for mesos, Alexander Rojas, Gastón Kleiman, Meng Zhu, Till

Bugs: MESOS-9146
https://issues.apache.org/jira/browse/MESOS-9146
Repository: mesos
Description
-------
There is not a lot of value in the master timing out a client's
authentication, other than releasing a small amount of resources.
We currently have a burned in 5 second timeout, which is largely
sufficient since most authenticators are implemented to use an
actor per session and avoid any head-of-line blocking.
Ideally, the master would know how long the client's timeout and
the master can use that for its own timeout. The current max backoff
for schedulers and agents is 1 minute, so this patch bumps the
master's timeout to be closer to that (15 seconds). We don't bump it
further because the vast majority of the timeout time is spent in
the initial trip through the master's queue, which occurs before
the master sets up its timeout.
This also adds a flag, both to allow users to tune this, as well
as to allow us to control timing in tests.
