Create a benchmark to test lite RPC

[godmodegalactus]

Create a benchmark system to easily test lite RPC.

The benchmark should have low tps mode, medium tps mode and high tps mode.

Compare confirmation stage for RPC implementation, Block implementation, Gossip implementation for time taken to confirm, reliability (i.e Number of transaction correctly confirmed and not confirmed).

Try stressing the testnet and check how each implementation perform under stress.
