Fixed a defect where handlers for SASL authentication were being added multiple times. This caused issues when trying to reconnect. A handler for the auth mech would get added each reconnection attempt, causing digest-md5, success and failure to be called x times for each x number of retries.

Handlers for sasl authentication as well as success and failure are now added during the __init__ method.
