add Contract Deployment Flow

[ronnno]

Should cover:

1. Deployment flow for user defined contract:
   1. Send Transaction to _Deployment contract - results in state entry for the new contract with source
      1. InterNode sync propagates this state to all nodes under consensus inside block state diff
   2. Subsequent calls to that contract VM:
      1. VM checks if contract binaries are available in volatile disk (contract binaries cache)
      2. If not available - pull sources from _Deployment contract state, compile and validate binary hashes (against stored hashes in _Deployment state)
      3. save binaries to volatile disk (contract binaries cache)
2. Native contracts:
   1. lazy deployment - flow
   2. Why - the rational for why "built-in" contracts are not simply included in genesis block
   3. Auto deployment relies on consensus so "read only" CallMethod cannot trigger lazy contract deployment.
   4. If inter-contract calls are supported for V1 - can one contract constructor deploy another contract?
