Subject: [PATCH] Expose prometheus generic builder.

 So that people can easily try newer prometheus version
 in overlays:

 self: super: {
   prometheus_2 = (super.callPackage <nixpkgs/pkgs/servers/monitoring/prometheus> {}).generic {
     version = "2.8.1";
     sha256 = "0x8w0qdh4lcf19nmdlhvgzpy08c2a932d3k49cjwhi5npcsf858n";
     doCheck = false;
   };
 }
