Support for `redis://` URIs

[pratul]

If I provide a redis:// style URI, I get an exception in RedisModeURIFactory#build. I've gone through the library source and it appears that such a URI scheme isn't supported out of the box -- even though Lettuce supports it.

However, I also cannot figure out how to pass the values from a deconstructed redis:// URI to the bundle during the Dropwizard initialization step. Any pointers?

Hey Pratul! Thanks for the issue. Without an error trace, this likely seems related to our usage of the Guava HostAndPort class, and seems like it might be a good motivator to move away from that class.

Hi—I know this issue has been open for a while, but I have the same request!

(I'm standing up a very small Dropwizard service that'll cache some data in Redis. All our other services receive Redis URIs via templated Helm charts; it would be perfect if we could do the same for this new one. I think I can kludge around it by using urlParse to decompose the URI, then interpolating the parts into the separate config fields that dropwizard-redis expects...but that's a little awkward).

I know Dropwizard is in stable maintenance mode, but this didn't feel super complicated or risky to add, so I gave it a go!
