Bridges - changes for Bridges V2 - relay client part (#4494)

Contains mainly changes/nits/refactors related to the relayer code (`client-substrate` and `lib-substrate-relay`) migrated from the Bridges V2 [branch](#4427). Relates to: paritytech/parity-bridges-common#2976 Companion: paritytech/parity-bridges-common#2988 ## TODO - [x] fix comments ## Questions - [x] Do we need more testing for client V2 stuff? If so, how/what is the ultimate test? @svyatonik - [x] check [comment](#4494 (comment)) for more testing --------- Co-authored-by: Svyatoslav Nikolsky <[email protected]> Co-authored-by: Serban Iorga <[email protected]>
