[improve][client] Adding support for token supplier for the AuthenticationToken

[Bouk250]

Master Issue: #396

Motivation

The AuthenticationToken only supports static token, limiting us to use token without expiration. So the integration with existing authentication returns tokens with expiration becomes not possible.

Modifications

Added the necessary cpp code for support token supplier as a js callback returns string tokens.

Modified file:

• index.d.ts - Update constructor signature for support TS.

• src/Authentication.cc - Implement the logic of communication between js callback and cpp token supplier.

  New file

  -src/TokenSupplier.h - Needed for the logic implementation. -examples/consummer_token.js - Example

  Verifying this change

• [ ] Make sure that the change passes the CI checks.

This change added tests and can be verified as follows:

• Added tow new test in the e2e file to cover token supplier (sync/async)

@shibd Hi :), I fixed the issue with the test, I forget to release the callback. Now it will work.
