Subject: [PATCH] properly detach containers from network on 'weave reset'
 since otherwise we are leaving veth pairs behind which a) breaks a subsequent
 'weave attach', and b) runs contrary to 'weave reset's stated purpose of
 removing all traces of weave.

NB: This does yank the ethwe interface from the containers.

Fixes #164
