Various code inspection resolutions (#7438)
* 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
