Feature Request: Bogart Server Side Caching

[soitgoes]

It'd be nice to be able to have an option on the route to specify how long to cache server side for and whether or not to vary by param etc.

This could have memory leak implications. I'm not sure how you take those out of the programmers hands though unless you outsourced the actual cache to redis or something.

It should be able to take different backends, so redis would be appropriate. I'll make the default be in-memory which will be fine for dev.
