Cost Explorer (Usage and Cost) update

[HollyJoyPhillips]

Summary: As we now have the endpoint for the Cost Explorer we need to update this section on the Billing tab in Analytics

Endpoint: https://dev.platformmarketplace.reapit.net/trafficevents/swagger/index.html
/billing/{month}

Location: https://dev.marketplace.reapit.cloud/developer/analytics/billing

• The ‘Month’ dropdown menu should only show months since and including the date the developer registered (created). For example, if the developer registered in ‘January 2020’ the dropdown menu would only display:
  May2020
  April 2020
  March2020
  February 2020
  January 2020

If a developer registered in ‘April 2020’ then it would only show:
May2020
April 2020

To populate the table:
We will need to query the billing/{month} endpoint by providing the applicationId(s) of all apps associated to that developer (like we are doing for the transaction history section) and specify the month (YYYY-MM) as per the selection from the dropdown menu

Based on the table layout we should use the following:
Resource = serviceName
Endpoints = endpointCount
API Calls = requestCount
Cost = cost

For the subsections to each Resource (serviceName) we should display the ‘requestsByEndpoint’
