Add gitlab ci configuration class that holds hash

As for now, we keep this class inside a oryginal config processor class.
We will move implementation to this class and delegate to it from
current config processor.

After original gitlab ci yaml processor not longer has relevant
impelemntation we will replace it with new configuration class.
