Proposal: modify metrics endpoints to make more similar

[kalantar]

To define data sources we have the following:

• HTTP:
  • URL: http://iter8.default:8080/httpDashboard
  • query string: namespace=ns&experiment=test_name
• gRPC:
  • URL: http://iter8.default:8080/grpcDashboard
  • query string: namespace=ns&experiment=test_name
• A/B/n:
  • URL: http://iter8.default:8080/metrics
  • query string: application=ns%2Fapp

I wondered if we wanted to regularize this:

• For A/B/n use abnDashboard instead of metrics as the endpoint
• For A/B/n change structure of query string to be namespace=ns&application=app
• change experiement to test or performance_test
• Not sure how to make the second parameter the same; but there is no real need to
