Command line test runner - Support a well known report output format

[felickz]

Feature request to support a common test output format from the command line test runner.

• JUnit
• xUnit 2
• NUnit 2
• NUnit 3
• Visual Studio Test Results (TRX)
• FxCopReport format CodeAnalysisReport.xsl (c:\program files (x86)\microsoft visual studio\2017\enterprise\team tools\static analysis tools\fxcop\Xml\CodeAnalysisReport.xsl)

This would enable test results to be reported as part of VSTS Test dashboards using CI/CD Release Pipelines

• Config - Publish Test Results Step
• Test Results - Release Pipeline Dashboards

Thinking that we will support the SARIF format first to cover static test results. There is likely a plugin for most build pipelines that will support this.

SARIF support added to the parser project. Next up is to document how to parse this format using the various CI systems.
