Create a github publish workflow for releasing the InferenceSystem docker container

[dthaler]

After addressing issues #319 and #321, we should create a workflow to

• publish the InferenceSystem docker container to the Azure Container Registry, and
• deploy an updated docker build to Azure Kubernetes Service.

The trigger would be a manual action to release a new build, e.g.:

on:
  push:
    tags:
      - 'v[0-9]+.[0-9]+.[0-9]+'
