Support set connectionTimeout param

[shibd]

Motivation

In the C++ client, the connectionTimeout parameter controls the time allowed to establish a connection, with a default value of 10 seconds

https://github.com/apache/pulsar-client-cpp/blob/4ba83e83fbb4319c0b4cda82372caf042e9ccaa6/lib/ClientConnection.cc#L184-L185

We need to expose this config on node.js client.

Modifications

• The pulsar_client structure definition from the C++ client has been copied, allowing node.js client to set it using the C++ API instead of the C API.
• Expose connectionTimeoutMs configuration
