Notary service in chains

Notary service is a service that provides on-chain network assistance to form multisignature transactions. Inner Ring (Alphabet) nodes use multisignature transactions to create containers, approve balance changes, update network map, tick epochs, etc. With notary service, it takes up to seven times fewer transactions to do these operations. Notary service calculates the exact amount of GAS to execute transaction, therefore operations are cheaper (withdraw fee with notary is less than 0.5 GAS; withdraw fee without notary is up to 7.0 GAS).

Currently, frostfs-dev-env contains single chain (see morph service) and it enables notary service from the genesis block.

To enable notary service, use neo-go configuration below.
