Payload Embedding & Propagation on Native P2P

[fuxingloh]

What would you like to be added:

Native Block Structure must support DMC Payload. DMCHandler() implemented on DeFiCh/ain called upon by "miner" during minting and connecting. DMCHandler() interacts via JSON-RPC #80 using the methods defined in #89.

DeFiCh/ain test plan includes using the python testing framework on area/ain for the new block structure to accommodate native side testing for DMC.

The should include:

• Payload Embedding
• Payload Propagation on Native P2P via embedded transaction
• DMCHandler() for Connecting Block to EVM
• DMCHandler() for Mining Block from EVM
