new-api: execute a process inside an existing container
...
A new constructor function (like nsenter) is added in this patch. This
function gets arguments from environment variables and its behaviour doesn't
depend on a command line arguments.
A program which calls factory.StartInitialization() must import the nsenter
package. It looks ugly, but I don't know another way how to enter into CT from
a go code.

Use namespace.Exec() and namespace.Init() to execute processes in CT.
Now an init process is actually executed in a new container. This series

This changes the namespace configuration on the config to include the
