Run single Pester test

[nohwnd]

PR Summary

Add support for Pester v5 to run single test, all tests in any describe or all tests in via the task.

The VSCodeMarker is not provided. The Pester side would work, but the highlighting (or what was it for) does not work in VSCode, and so it only makes the output uglier, with stacktrace on the top.

To test this you need Pester v5 ( branch filter-by-lines or once merged v5.0), you will also need the updated lense from powershell services (branch same as here). Once your VSCode is started with the new version (after running the extension by F5), open a .Tests.ps1 file and load Pester v5.

This looks good to me, when are you targeting Pester 5 to come out?

The previous commit was broken it actually run all the files in the current path.
I added opt-in option for v5 lens, so people can enable it when they are ready to give Pester v5 a try, and don't have to be confused by having Run Test on their It blocks that does not actually run.

I hope that it is okay to put the settings on language server settings object, because that is where the majority of other settings are, and it required least amount of changes to the code.

While I was at it I also added output option for verbosity. All the settings work for both v4 and v5 and were tested with the other PR in powershell editor services. The expected behavior is:

• Nothing will change with the default settings.
• User can change verbosity to print everything (failed, describe descritions, summary etc.) except for Passed tests, by setting the Minimal verbosity on v4.
• User can run Pester v5 tests without enabling the opt-in option, but will only be able to run whole describes.
• User can enable the code lens, and run any block and any test. This requires pester v5 if no Pester is loaded, and warns if older version is loaded.
• User can set verbosity to minimal, and see just failed tests + summary.

If this gets merged when can I expect it in PowerShell preview extension? It would be nice to have so I can use it without running VSCode in VSCode. I think I will also soon release v5-beta. Released.

I need to move this file into PSES repo so it can be signed. If you'd like to sign up to do that, that'd be great, otherwise, hopefully we can get this PR in soon so I can move it.
