Add a Laravel Cache Adapter

[pselge-5anker]

adds an optional Laravel Cache Adapter that plugs right in and supports all of the available illuminate/cache drivers.

Cool idea! But could we take this a step further and instead of pinning it to laraval, use PSR? illuminate/cache implements psr/simple-cache a.k.a. PSR 16. That allows to use e.g. symfony/cache , too. WDYT?
