Merge coverage reports from multiple runs

Required Information

Type: bug Enter Task Name: PublishCodeCoverageResults@1

Environment

• Server - Azure Pipelines

Issue Description

Task PublishCodeCoverageResults@1 supports reports from multiple files, but the summary just shows the first match.

Task logs

The behavior for a task configured with a wildcard path for the coverage file is a little inconsistent:

      - task: PublishCodeCoverageResults@1
        inputs:
          codeCoverageTool: cobertura
          summaryFileLocation: $(System.DefaultWorkingDirectory)/packages/*/build/coverage/coverage.cobertura.xml

In this example, there are few coverage.cobertura.xml files from separate test runs. Unfortunately, I receive warning:

##[warning]Multiple file or directory matches were found. Using the first match: ```

Ideally, the summary would show the coverage for each assembly separately. Because I'm working in a monorepo and would like to trace multiple folders separately.

It only merge files before publishing? If I have multiple jobs it means it won't work? For example, PublishTestResults works fine with multiple jobs if you set mergeTestResults=true
