Earlier testing of parameter compatibility

[alx9r]

Currently parameters specified in configuration documents are not checked for compatibility with the corresponding resource if and when the resource is invoked. Basic checking for parameter compatibility should be performed when the parameters are bound to the resource. That way parameter errors in configuration documents are detected as early as possible.

[alx9r]

This example invokes ConfigInstructions with a bogus parameter:

ConfigInstructions this_should_throw {
    Get-DscResource TestStub ZeroDsc | Import-DscResource

    TestStub bogus_param @{
        Key = 'some key'
        Bogus = 'bogus'
    }
}

It should throw an exception but does not.
