Add support for querying for test output from AzureDevops public cloud

We would like to be able to run tests in many different CI environments (to encourage testing 'everywhere' and to leverage resources at our disposal, https://dev.azure.com/adoptopenjdk).

This issue is an enhancement to TRSS to be able to query the AzDo API, much like it currently queries the Jenkins API, for monitoring tests in that CI environment.

There are still some open questions related to this enhancement that need to be answered that will be listed below.

Start by reviewing how TRSS currently queries the Jenkins API and compare that entry point with the Azure DevOps API. Resolve the open questions in this issue and define the required test-output querying and monitoring behavior before implementation.
