* Rename waku_api to rest_api and underlying rest to endpoint for clearity * Rename node/api to node/kernel_api to suggest that it is an internal accessor to node interface + make everything compile after renaming * make waku api a top level import * fix use of relative path imports and use default to root rather in case of waku and tools modules
