cgroups: set a freezer state before calling FreezerGroup.Set()
...
My previous patch moved the setting of the freezer state after the Set()
command. It's wrong, because this command uses it, so we need to set the
freezer state before the command and rollback it in an error case.

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.
