Review request for mesos, Avinash sridharan, James DeFelice, and Qian Zhang.

Bugs: MESOS-7605

Repository: mesos


Added a new UTS namespace isolator that can be used to
guarantee that a task gets a UTS namespace. CNI deals with
UTS namespaces when a task gets a container rootfs, and also
properly configures a container hostname, so this isolator
deals with the remainin case, which is when the task doesn't
have a container image. In this case, we will retain the host's
hostname configuration but protect it from the task by placing
the task in a private UTS namespace.
