Add Health Check Command to NSX plugin
The NSX plugin does not support the HeathCheckCommand. Instead it fakes a
PingCommand as a call tot he control cluster status API.
However, we have seen in production that the management server will
sometimes find the NSX controller to be behind on ping and that will trigger a
HealthCheckCommand which will return with an unsupported command answer.
Once this happens the controller is put into Alert state and will not
recover until the management sever is restarted.
In addition, during the investigation, there will be a null pointer
exception due tot he fact that the NSX controllers do not live in a pod.
This PR tries to address those two issues.

When investigators kick-in an exception is thrown because of the
missing pod foreign key.
