func kubernetes deploy erroneously creates multiple deployments for a single project

Example:

I have a single project that exposes a http trigger for healthcheck/readiness check (for k8s), and an event hub trigger to consume messages from an event hub.

Running func kubernetes deploy will generate 2 x deployment manifests: one for each trigger, even though both are in the same binary - obviously this results in duplicate instances of the triggers, as each deployment will have both. The tool should be generating a single deployment.

Start at the `func kubernetes deploy` command and trace how one project’s HTTP and Event Hub triggers are converted into deployment manifests. Reproduce the example with both triggers; done means one deployment manifest is generated for the binary and duplicate trigger instances are not created.
