Badge Request: Azure DevOps Test Results

[mehmetseckin]

📋 Description
Heavily inspired by #2237, I would like to propose test result badges for Azure Pipelines builds. I have been working on a proof-of-concept, so I'd love to add this functionality myself, or help along the way.

• Which service is this badge for?
  Azure DevOps (Azure Pipelines)

• What sort of information should this badge show?
  Summary of test results, e.g.:
  
  

  It would be nice to have the compact_message feature like the appveyor tests service:
  

🔗 Data

• Is there a public API?
  Yes, but it is undocumented. Here is an example request:

https://dev.azure.com/azuredevops-powershell/azuredevops-powershell/_apis/test/ResultSummaryByBuild?buildId=20

This returns an aggregated analysis object which can be parsed to form the badge.

{
    "aggregatedResultsAnalysis": {
         "totalCount": 22,
         "resultsByOutcome": {
             "Passed": {
                  "count": 20
              },
             "Failed": {
                  "count": 1
              }
         }
     }
}

• Does the API requires an API key?
  Only for private projects.

Nice @mehmetseckin I was hoping this would materialize but didn't see the API in the docs so I thought this would be blocked. Good find!
