MESOS-3046 (Stout's UUID re-seeds a new random generator during each call to 
UUID::random)

    https://issues.apache.org/jira/browse/MESOS-3046


Repository: mesos


Description (updated)
-------

__Phenomenon:__
Performance downgrade

__Root Cause:__
stout's UUID abstraction is re-seeding the random generator during each call to 
UUID::random(), which is really expensive.

__Solution:__
Seeding the random generator only once per thread.
