Issue MESOS-3083: Doing 'clone' on Linux with the CLONE_NEWUSER namespace type can drop root privileges.
The namespace tests attempt to clone a process with all namespaces that are available from the kernel which includes the 'user' namespace in Ubuntu 14.04 which causes the child process to be user 'nobody' instead of user 'root' after invoking 'clone' which is bad because the test requires that the child process is 'root' and so things fail (because of insufficient permissions). For now, we explicitly ignore the 'user' namespace in the tests, but this issue is to track exactly how we might want to manage this going forward.
