Redis caching instead of File cache

[cristianowa]

Is your feature request related to a problem? Please describe.
We used File Cache in a Docker image with read-only enabled.
This lead to an error when starting the application.
We tweaked the Dockerfile so that directory is writeable, but we wondered if could use another caching system - our system already has Redis available.
Moreover, a common cache could help improving performance.

Describe the solution you'd like
Extend the BaseCache to RedisCache, receiving Redis URL and credentials when instantiating the class.

Describe alternatives you've considered
Extending locally the class and consuming it. It works, but it seems something someone else could use as well.

I think you can replace the file cache with your own implementation: https://gh.getunleash.io/unleash-client-python/customcache.html

Does that solve your problem?

[cristianowa]

@FredrikOseberg It will solve my project and that is my plan.

My question is:
Is it worth having other cache types available in the package aside from Filecache?

Basically, I want to save the work I'm having implementing the custom cache for Redis for other people.
