InferenceSystem should query hydrophone metadata from orcasite

[dthaler]

Currently adding a new hydrophone requires code changes in a bunch of different places. Currently hydrophone metadata is hard coded in:

• deploy\configmap.yaml
• demos\hls_reader.py
• deploy-aci.yaml
• deploy\*.yaml
• misc\make_tsv_from_json.py
• src\LiveInferenceOrchestrator.py
• src\globals.py
• src\model\datautils.py
• src\PrepareDataForPredictionExplorer.py

Orcasite already has the metadata and the danger is it could get out of sync if a database change is made without changing the InferenceSystem code. Instead of requiring code changes, the metadata can be dynamically looked up via the https://live.orcasound.net/api/json/feeds API, using the docker container namespace to find the entry with the matching slug. The NotificationSystem is already doing that, but the InferenceSystem is not.
