Support for passing custom provider auth credentials from Python client

[tncyclk]

I want to write a Python client for a pulsar server written with BasicAuth mean custom auth (authenticationMethods=customAuth) that authenticates with userId and password params. I wrote the following code for this, but it did not work.

import pulsar
from pulsar import Authentication
import logging

logging.basicConfig(level=logging.DEBUG, format='%(asctime)s - %(levelname)s - %(message)s')

class CustomAuthProvider(Authentication):
    def __init__(self, username, password):
        self.userId = username
        self.password = password
        self.auth_type = "customAuth"
        self.auth = self.get_auth_data()

    def get_auth_data(self):
        return pulsar.BasicAuthAuthentication(self.userId, self.password)

    def auth_method_name(self):
        return self.auth_type
    

class Messenger():
    def __init__(self) -> None:
        
        self.pulsar_server_url = "pulsar://192.168.56.1:6650"
        self.client = None

        self.username = "user"
        self.password = "95ce64b2-69a9-3c4e-8e2e-ab244acfdd99"

    def connect_to_server(self):

        auth_provider = CustomAuthProvider(self.username, self.password)

        try:
            logging.info("Trying to connect to Pulsar...")
            self.client = pulsar.Client(
                self.pulsar_server_url,
                authentication=auth_provider
            )

            logging.info("Connected to Pulsar server!")
        except Exception as e:
            logging.error(f"Failed to connect to Pulsar: {str(e)}")

        if self.client:
            logging.debug(f"Client object: {self.client}")

if __name__ == '__main__':
    app = Messenger()
    app.connect_to_server()

Also, the broker conf I made for custom CustomAuthProvider is as follows.

### --- Authentication --- ###
authenticationEnabled=true

# Specify the authentication providers to use
authenticationProviders=com.liderahenkpulsar.auth.BasicAuthProvider

# Define the authentication method name that matches your AuthenticationBasicAuth class
# This should match the value returned by getAuthMethodName()
authenticationMethods=customAuth
# Authentication settings of the broker itself. Used when the broker connects to other brokers,
# either in same or other clusters
brokerClientAuthenticationPlugin=com.liderahenkpulsar.auth.AuthenticationBasicAuth 
brokerClientAuthenticationParameters=

Please give support in Python client for sending basic auth credentials while connecting to server with userId and password.
