Add TOTP MFA authentication support to Python driver

[sharmagot]

1. Vertica supports TOTP-based authentication as part of multi-factor authentication (MFA).

2. To enable MFA for a new user, create the user with the following command:

CREATE USER ravi IDENTIFIED BY 'vertica' ENFORCEMFA;

3. After the user is created, the generated secret key must be added to a TOTP app like Microsoft Authenticator.

4. The TOTP app will generate a time-based code every 30 seconds, which is required during user login.

Why Go Unit tests "Corresponding Go unit tests have been added to validate the TOTP-based authentication flow." ??

Please correct this in the description.

Overall, excellent structure — just minor cleanups needed for polish and safety

Since, the Git pipelines are failing, I would like to see the local test suite results for the new and existing test cases to avoid regressions.

Hi Mani , I have updated the code based on your review comment.

[mkottakota1]
