d572094b75 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.

5ecd29c1f2 linux_container: fork an init process in a new set of namespaces 
Use namespace.Exec() and namespace.Init() to execute processes in CT.

Now an init process is actually executed in a new container. This series
doesn't change code about creating containers, it only reworks code according
with new API.
