Allow for generic dynamic tag for testing frameworks to fill in data

Allows for user to define a name and API endpoints for a dynamic tag that can be populated arbitrarily with test results for a request. Also allows for API endpoints so that the tag can link to a detailed results page of the tests.
It's possible. My planned endpoint is currently http-only currently, so making an async call from JS throws an error and fails. I can potentially cache on the api-side if slowness becomes an issue, but it's still possible.
