Allow configurable pester verbosity (and ideally inherit from Powershell extension)

[JustinGrote]

When I click the run for the tests, I prefer detailed to normal output. There should be settings to mirror these settings and ideally inherit these settings if not explicity set otherwise.

So luckily the Debug Output Verbosity is used already because vscode-pester-test-adapter uses the PowerShell extension for debugging.

The next change would be to hook up powershell.pester.outputVerbosity to vscode-pester-test-adapter. Pretty simple to do, I think:

const value = vscode.workspace.getConfiguration('powershell').get<string>('pester.outputVerbosity');

and then pass that in to the script:

vscode-pester-test-adapter/src/powershellScripts.ts

Line 110 in dfd4a1f

export function GetPesterInvokeScript(scriptPath: string, outputPath: string, lineNumber?: string): string {

Interested in touching a little typescript? :)

@TylerLeonhardt if it annoys me enough, maybe :)
