[keycloak-dev] xa-datasource requirement

The User Storage Provider SPI example uses a different datasource than KeycloakDS. What I found is that switching Keycloak to use JTA creates a problem. If you have 2 non-xa datasources in the same JTA transaction, Wildfly barfs. It doesn't allow it. The workaround is have only one non-xa datasources and have all the rest be xa datasources, or to make them all be xa-datasources. I'm changing the KeycloakDS to be an xa-datasource. I don't think this will effect anybody's application, although i'll need to note in documentation that this is required and changed. Bill
