[WFCORE-231] Add support to specify the sasl-protocol and server-name on the individual connector.


Note:  This is crying out for some additional re-factoring for clean up but at the moment I am trying to keep in a state that is easier to merge into EAP.
Fine if that is the case but so far it appears we have only had 1.1, 1.2, 1.3, and 2.1
