Orphaning elasticsearch

Hi, folks.

A while back, I realized that I was the main admin for the elasticsearch
package. Given that I'm not using elasticsearch these days (I signed up for
co-maintainership because I maintain the perl bindings for ES) and with the
upcoming retiring of most of the Java stack in Fedora, I just don't have the
cycles to deal with this and I've decided to orphan the package.

If any one of you wants to step up and become main admin, speak up in the
coming days and we'll make it happen.
