feat(Consensus): Add function to get consensus version. (#413)

* feat(Consensus): Add function to get conmsensus version. Get vm/abi based on node protocol

* chore(node): Remove logs

* add docs for node getProtocol

* disable channel tests

* try to fix channel test

* try to fix channel test

* Make sdk compatible with node from 2.3.0 to 4.0.0

* feat(TxBuilder): INT type must be greater or equal 0 int transaction
