feat: add Redis component

[owenvoke]

Closes laravel-zero/website#39

[nunomaduro]

@owenvoke Would this feature would be useful for people? Can you give me a snippet example?

[owenvoke]

I probably wouldn't use it, but back on laravel-zero/website#39 you mentioned it would be nice as a component.

[nunomaduro]

My question is more like: After people install the component. What code can they use to use redis?

[owenvoke]

Ohhh. Whoops. I guess they can use it with the queue or database components. For example you could make a CLI tool for viewing or managing Redis tasks.
https://laravel.com/docs/8.x/redis

Or you could use the facade with Redis::get() or Redis::set() for storing any data.

[nunomaduro]

Makes sense. So let's make sure you put those on docs. Looks good to merge.

[owenvoke]

I'll write the docs for this later and then merge. 👍🏻 Thanks Nuno.
