* remove unused code * remove defer use in loop * Remove unused methods and constants * gofmt and gaz * nilness check * remove unused args * Add TODO for refactoring subscribeWithBase to remove unused arg. It seems too involved to include in this sweeping PR. https://github.com/prysmaticlabs/prysm/issues/7437 * replace empty slice declaration * Remove unnecessary type conversions * remove redundant type declaration * rename receivers to be consistent * Remove bootnode query tool. It is now obsolete by discv5 * Remove relay node. It is no longer used or supported * Revert "Remove relay node. It is no longer used or supported" This reverts commit 4bd7717334dad85ef4766ed9bc4da711fb5fa810. * Delete unused test directory * Delete unsupported gcp startup script * Delete old k8s script * build fixes * fix build * go mod tidy * revert slasher/db/kv/block_header.go * fix build * remove redundant nil check * combine func args Co-authored-by: prylabs-bulldozer[bot] <58059840+prylabs-bulldozer[bot]@users.noreply.github.com> Co-authored-by: Victor Farazdagi <simple.square@gmail.com>
