v0.4.0

[Nana-EC]

This release brings greater stability to the relay with Schema updates and initial Ethereum dev tool support.

The schema response formats for Transaction receipt and Logs were updated to match the Ethereum Execution APIs.

The eth_call endpoint logic was expanded to gracefully manage calls where the data field is left empty.
The eth_sendRawTransaction endpoint precheck logic was expanded to ensure the minimum gas requirement is satisfied.

Initial Ethereum tool support was explored with base coverage for Hardhat.
With this smart contracts can be deployed and executed on the Hedera Network by configuring Hardhat to route through the relay.

Deployment metrics coverage was expanded to note the relay operator account_id.

Acceptance and integration test coverage was also increased to provide greater confidence across deployments.
