feat(connector-iroha2): add support for Iroha V2

- Add new Iroha V2 cactus connector.
- Add endpoints `transact` and `query`. Both endpoints support
  critical subset of instructions and queries supported by the upstream javascript iroha sdk.
  Transaction can be awaited or can return immediately.
- Add new endpoint `generate-transaction`, to create unsigned transactions
  that can be signed on the client side.
- Add a function to iroha2-connector package to help signing iroha transactions
  on the client (BLP) side.
- One SocketIO endpoint can be used to monitor new blocks from the ledger.
- Add new helper method for signing query payload on the client side.
- New connector can be used through a verifier-client interface.
- All added functions are tested in functional test suites and documented.
- Add test for complex scenario that involves creating new account and asset, and then transfering
  assets between two accounts.
- Add test for parsing retrieved block data to find specific transaction hashes.
- Added execution of Iroha2 tests to the CI.

Additional notes:
- Iroha V2 javascript packages are not available on official npm yet, had to include `.npmrc` with
  private npm address. I'm not sure if there's ETA of delivering these through NPM, so it might be
  necessary to commit it after all.

Closes hyperledger-cacti#2138
Depends on hyperledger-cacti#2140
