Add support for `dotnet test` to have JUnit style output

The Problem

Using CircleCI as a build tool, there are some features you can only get access to if your test output is in a JUnit format. XUnit provides a -junit argument to transform XUnit output to a JUnit style of output and it seems similar functionality used to be supported: https://stackoverflow.com/questions/39542533/xunit-dotnet-test-cli-to-output-to-nunit-xml-so-that-bamboo-can-read-the-results/47073101

I’ve tried using the --logger option in a few ways, but can’t find a way of achieving what I want without using another package.

Is it possible to use the XUnit Transforms out the box with dotnet test?

Expected behavior

• To be able to run an argument as part of dotnet test that enables the test output to be transformed into an expected format.

Actual behavior

• Can use the --logger argument to output to xml or trx, but the tool I’m using explicitly needs a trx with JUnit formatting

@danjcosg to output in JUnit format you can add a reference to the JUnit Logger nuget package in your test project and then use the following command to run tests dotnet test --test-adapter-path:. --logger:junit
