Add support for configuring Pester's SkipRemainingOnFailure and Verbosity options

[joshooaj]

The Pester configuration option Output.Verbosity is hard-coded to Detailed which can make it difficult to identify which test failed in the case where you have hundreds or thousands of tests (especially when running automatically generated documentation tests).

In some cases you might also want to stop running tests as soon as you hit the first failed test rather than wait for all tests to complete. Pester has the Run.SkipRemainingOnFailure option that can be set to Run if all remaining tests from all containers in the run should be skipped, or Container or Block for a more narrow scope.

I'd like to be able to configure these options like so...

Properties {
    $PSBPreference.Test.SkipRemainingOnFailure = 'Run'
    $PSBPreference.Test.OutputVerbosity = 'Normal'
}

I'll submit a PR for review shortly.

I was thinking it would be nice to be able to provide Pester configuration object.

I was thinking about that too. Tag all the current parameters on Test-PSBuildPester with a ParameterSetName and create a second parameterset that accepts a PesterConfiguration object?

Then maybe have a $PSBPreference.Test.Configuration value that, if not $null, is passed to Test-PSBuildPester instead of splatting the individual options like we do today?
