Follow-up on: https://r3-cev.atlassian.net/browse/ENT-5331
Decrease the memory footprint of Corda in development mode.
The acceptance criteria for this improvement are as specified in this ticket: https://r3-cev.atlassian.net/browse/FEAT-366
Specifically, with the new improved version of Corda, one should be able to spin up 4 nodes locally in a bootstrapped network and perform some transactions on a machine with 8GB of memory.
Note: this should be done primarily on OS, which is what people use when exploring Corda. Any gains should be passed on to ENT.
