Document if the non-Elytron SASL implementations are supported in EAP and its clients.
Users should be informed if (or which) configurations with non-Elytron SASL mechanisms are supported.

SASL mechanism implementations in Java are registered by security providers. The EAP7-530 comes with a set of Elytron implementations, nevertheless there probably exists other implementations coming from another security providers. (E.g. the ones present in Oracle JDK).
