set up rest API for data access in k8s

The plan is to deliver data to the app in JSON format using a REST API. My understanding is that @jamcinnes2 has configured one. Need to add that to the kubernetes deployment as another service. This mainly involves:

• [x] find where the rest service has been defined
  • likely rest endpoint is: https://hwitw-dev.arcticdata.io/wxapp/getwxvar?vlat=58.3&vlong=-134.4
  • note that currently that always returns the same JSON file
• [x] wrap that in a kubernetes deployment and service (may be able to use existing for the static webapp)
• [x] create an ingress endpoint for that service (probably can use existing ingress for the static webapp)
• [x] ensure the service has access to a PVC for the CephFS mount containing the data (read-only)

So, right now, the main issue seems to be to mount the data volume and reimplement wxdata.get_wxvar() to access that data. In doing that, it would be good to:

• [x] identify existing methods that can convert the netcdf data to the json format
  • likely refactor from locjtool.py

Rest service is up and running for delivering JSON data at https://hwitw-dev.arcticdata.io/wxapp/getwxvar?vlat=58.3&vlong=-134.4
