Commit e515acd7be347ba853dcb3b7cc26d277e6d4d2b9 in branch refs/heads/master
from [~yasker]

CLOUDSTACK-4199: Only use ifdown/ifup for the un-configured eth2
Seems the behavior of ifdown/ifup changed in new version, that it would only
enable the default IP of eth2, regardless we can configure additional ips for
it. So we would always use ifconfig for interface control whenever
possible(a.k.a eth2 already got ip addresses).
When VR is booting up, ipassoc command hasn't been delivered, it's possible that
eth2 doesn't have any ip address, then ifconfig would fail because it doesn't
know how to find the ip for eth2. So in this only case, we would use ifdown/ifup
to set the ip address according to /etc/network/interfaces.
It can potentially racy againest ipassoc command, but biglock should prevent
racy condition from happening.
