feat(connector-Besu) Load contract instances from compiled contract files

[kikoncuo]

Parent: feat(cactus): Standardized common interface functionality transaction across connectors #604
This is a dependency for #609

Description:
Using the .json files generated from compiling a Solidity smart contract, the Besu/Quorum connector plugin should be able to load web3 smart contract instances in the constructors, write them using the keystore plugin, store them in a map and use them to generate the transactions simplifying the usage vs providing the abi in a per transaction basis.

Acceptance criteria:

• Contracts are loaded from a folder and invokable by using their contract name.

To solve this task, we need to modify the deploy function to update the networks field in the compiled contract .json file, like other SDKs do (https://trufflesuite.github.io/artifact-updates/requirements/truffle.html). This is necessary to recover the contract instance deployed on the blockchain from the compiled contract file.
