Support Connecting to Redis via Unix Socket

@dpipemazo Let me add additional Client type for socket connection and will send you branch to try. Give me 15 minutes.

Works great! 🎉

Thank you!!

@dpipemazo Redis Data Source based on Radix golang client (https://github.com/mediocregopher/radix). I don't see an option to connect using the Unix Socket at first sight. If it is supported by Radix, it would be ideal.

I can take a closer look later, but we can ask Radix developer if it's something he would be interested to implement. I see that some Redis clients support connecting using a Unix socket.

Yes, I agree it should come from the client. We've been using redis-py and hiredis via the unix socket for a while with good success, makes sense this support isn't in all of the language clients, particularly a language like golang which is really geared at networked connections. I'll file an issue over there. Thanks!

@dpipemazo Thank you for submitting the issue for radix. Looks like we found the way how we can add Socket connection as an additional client type.
I will test and let you know later tonight.
