RFS: ruby-redis - new upstream release + patch to fix RC

[Jonas Genannt <jonas.genannt@capi2name.de>]

Hello,

could any dd please have a look at ruby-redis:

 ruby-redis (3.1.0-1) unstable; urgency=medium
 .
   * Team upload.
   * Imported Upstream version 3.1.0
   * d/control: wrap-sort
   * added patch to use random port on unit tests (Closes: #755320)


I created a patch for the RC bug and send it to upstream, I also imported a new version.

Thanks,
	Jonas
