Some Neutron plugins require controllers and multiple backend services
to operate correctly. This patch adds the framework for third party
plugins to run sanity checks after Neutron Server has started.
This simple addition may reveal potential configuration pitfalls
much earlier in the dev/test cycle, thus speeding up the build
churn process.
The first plugin that uses this framework is the VMware NSX one.
