Now CT starts in a new user namespace. This allows us
* to remove our capabilities (CAP_VE_*)
* to improve security of our containers, because a process doesn't have privileges outside the container

Here is a good article about user namespaces https://lwn.net/Articles/532593/


Users should not notice these changes, everything should work as before.


* need to execute tests to check security of containers

* execute all tests, because these changes are touching very general parts
