Problem:
Start sending product telemetry to the product F5 telemetry service.

Solution:
- Use the production telemetry endpoint in production NGF image, built
  using:
  - goreleaser
  - make commands from building the images doc
- Introduce new targets in the Makefile for building prod images.

Developer instructions for building NGF image remain unchanged, and
such image will not send any telemetry, but will report it in the logs
at the debug level.

Testing:
- Confirmed production NGF image built using make command sends
  telemetry.
- Confirmed developer NGF image build using make command doesn't send
  any telemetry but reports it in the logs.
