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

* 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
