feat(besu): 🎸 OpenAPI support => arbitrary TX, contract deployments

This brings the besu connector to feature parity with the quorum
connector which already had these features supported (the code is mostly
taken from the Quorum connector because both Besu and Quorum connectors
are using Web3 under the hood so they share most of the logic/OpenAPI
definitions, etc.\nDifferences between the two will come out once we
start implementing private transactions and the other features that are
unique to the ledgers are not present/supported by vanilla
Web3.\nPerhaps it would be good to somehow have a third package that
allows for both Besu and Quorum connectors to re-use the vanilla Web3
specific parts instead of copy pasting, but this is a shortcut that was
deemed acceptable for now as we are ramping up for the v0.2.0 release.
