Review request for mesos and Jie Yu.


Bugs: MESOS-6556
    https://issues.apache.org/jira/browse/MESOS-6556


Repository: mesos


Description
-------

Implement a very simple namespaces/uts isolator that can be used to set
the hostname and domainname of a container without the necessity of a
CNI plugin.

Since we already had a `hostname` field in the ContainerInfo, we can
use that to set the host name once we are in the UTS namespace. Add a
corresponding `domainname` to the ContainerInfo to allow setting the
domain name.
