[Devel] [PATCH VZ10 3/3] ve_namespace: Allow entering non-running VE namespace

[Vladimir Riabchun]

This doesn't bring a lot of value and makes tests more complex.
To enter VE namespace we need to actually start VE.

In vzctl we have locking to prevent parallel creations.
If someone decides to skip locks and start one CT
in parallel - big mistake, but not ours.
