Live deploy as a nightly version

I've added the live deploy option as a nightly version. This future is enabled by setting the "live-deploy-mode" flag to true.

I would suggest instead a static method on LiveDeployManager:

    LiveDeployManager.startLiveDeploy(_resource);

I think you can then remove the `initLiveDeploy()` method above. The first time a container is deployed, the LiveDeployManager can start listening on `_resource.workspace`.
