Phpstan extra config values

[ndench]

Phpstan allows for more than just parameters in the phpstan.neon file. For example see phpstan's own phpstan.neon:

includes:
	- ../vendor/phpstan/phpstan-php-parser/extension.neon
	- ../vendor/phpstan/phpstan-phpunit/extension.neon
	- ../vendor/phpstan/phpstan-phpunit/rules.neon
	- ../vendor/phpstan/phpstan-phpunit/strictRules.neon
	- ../vendor/phpstan/phpstan-strict-rules/rules.neon
parameters:
	bootstrap: %rootDir%/tests/phpstan-bootstrap.php
	excludes_analyse:
		- %rootDir%/tests/*/data/*
		- %rootDir%/tests/PHPStan/Analyser/traits/*
		- %rootDir%/tests/notAutoloaded/*
	ignoreErrors:
		- '#Constant PHPSTAN_TEST_CONSTANT not found#'
		- '#Strict comparison using === between PhpParser\\Node\\Expr\\ArrayItem and null will always evaluate to false#'
		- '#Dynamic call to static method PHPUnit\\Framework\\#'
	tmpDir: %rootDir%/tmp
services:
	-
		class: PHPStan\Build\ServiceLocatorDynamicReturnTypeExtension
		tags:
			- phpstan.broker.dynamicMethodReturnTypeExtension

It also has things like includes and services. However phpqa ignores everything that's not in `parameters.

It would be really great if phpqa supported the entire phpstan config because you can do cool things like include phpstan-strict-rules and create custom rules.
