Specify which cache store should be used

[msschl]

Details

• Added a feature which allows users to specify a cache store other than the apps default cache.
• The cache key should not only be serialized, it should also be hashed. Some cache stores have a limited key length, for example the database store has a key length of 255 characters. The md5 hash function seems to be pretty good for this purpose, since it hashes fast and produces a string of 32 characters.

Hi @msschl, thanks for this PR. This is a good idea. However, I would like to implement it the same way as I have in the laravel-model-caching package:

• use sha1 for the keys
• add hash-collision-prevention logic

I can go ahead and implement that on top of your PR, if you like, but I won't be able to get to it until next week.

Thanks for submitting this!
