SonicV2Connector.connect method keeps on connecting infinitely even with wrong password.

[kamalkrbh]

If created SonicV2Connector object with wrong password and try connecting to a database like following:
sonic_db=swsssdk.SonicV2Connector(password="wrong_password")
sonic_db.connect("COUNTERS_DB")

swsssdk infinitely logging following warning messages and application is blocked forever, In case of wrong password a specific exception should be raised and function interface.py->_persistent_connect() should return immediately rather than retrying infinitely.

[2022-09-13 16:37:21,960][WARNING][swsssdk] Connecting to DB '2 COUNTERS_DB' failed, will retry in 10s
