v0.9.0

[Nana-EC]

v0.9.0 of the Hedera JSON RPC Relay brings improvements to the eth_getBalance and eth_getTransactionCount as well as increased support for metrics and rate limiting.

eth_getBalance was updated with support to filter search based on blockNumberOrTag, thus allowing for historic balance queries against the Mirror Node.

eth_getTransactionCount was updated to query the Mirror Node instead on consensus nodes, further more reducing the expenses by the relay.

The relay rate limit logic was expanded to include HBAR rate limiting. Now access to relay calls can be more evenly spread by rate limiting accounts based on HBAR consumption.

The SDKClient transaction and transactionRecord execution logic was updated to use TransactionRecordQuery to help improve metrics and better capture costs for the relay account.

The Helm charts were updated to support rate limit configuration on deployment in kubernetes environments. With this relay runners can customize rate limit tier values and windows to their use case.

Multiple API response schema improvements were made to improve expected formats of outputs utilized by development client tools.
