Reduced memory footprint when running in cluster with Solo

Solo has the following high level requirement:

- Title: Reduced Minimum System Requirements (Enterprise Laptop)
- Description: Network simulation (current target 3 nodes, 1 mirror node, jsonrpc relay, explorer) operating on a 16gb(12gb VM space) 4 core laptop.

Currently in a single node network running the Mirror Node Monitor Pinger 25 TPS, a single Consensus Node will exceed 7 GB for memory. Due to Solo Q4 requirements we need this brought down significantly to achieve our goal of running a full 3 consensus node network all on a 16 GB / 4 Core laptop with 12 GB dedicated to VM space.

Please assist the Solo team in either configuring Consensus Node to have a reduced footprint or making changes to ensure Consensus Node will not inhibit Solo team from achieving their Q4 target.
