Conflux v2.3.4-testnet

Configuration Improvement

• Add configuration use_isolated_db_for_mpt_table. Setting it to true will reduce the disk usage.
  • Note that the first restart after setting this configuration will take several hours, and the feature is still being tested, so use with caution.

Transaction Pool Improvement

• Implement a new transaction pool packing strategy so transactions with higher gas prices are more likely to be packed.

RPC Improvement

• Fix a rare panic in RPC metrics.
• Only count core space transactions for cfx_gasPrice.
