v0.8.0

[Nana-EC]

v0.8.0 of the Hedera JSON RPC Relay exposes improvements around relay cost reduction, tool support and E2E test coverage support for HIP 514 scenarios.

Rate Limit support by IP was added. In this case a simple in memory map is used to honor the thresholds defined for the requests per a given window of time. This is an initial attempt to allow relay operators to more fairly distribute relay access.

The eth_getBalance endpoint was updated to query the mirror node api/v1/account endpoint to retrieve real time balance updates. This reduces the number of calls to network nodes.

The relay acceptances tests now have E2E support for all HIP 514 precompile functions. Additionally, the tests were updated to utilize 0.30.0 of services and 0.64.0. mirror node images.

We expanded our exploration efforts with an example of a subgraph to showcase an initial example of how The Graph could be connected to Hedera.
As part of this effort some improvements to the relay were added such as ensuring a 15m gas limit was enforced to transaction submissions.
