Looks like the pulsar-client-node can not run with the current pulsar master code

**Motivation**

Install the pulsar-client-node with latest pulsar-client-cpp failed.

We should have a CI to run the tests with the latest pulsar code to check the compatibility./

Reproduce the npm install failure with the latest pulsar-client-cpp, then inspect src/addon.cc and src/Message.h for the missing pulsar/c/message.h dependency. Review the existing CI and test configuration to determine how compatibility is checked. Done means CI runs the client tests against the latest Pulsar code and detects compatibility failures.
