Use an optional way to programatically load CDI injection of LRAParticipantRegistry

In Narayana LRA we use the CDI @Inject to get the LRAParticipantRegistry into the Service filter class
https://github.com/jbosstm/narayana/blob/master/rts/lra/jaxrs/src/main/java/io/narayana/lra/filter/ServerLRAFilter.java#L95

On way to get working the LRA WildFly extension - https://issues.redhat.com/browse/WFLY-14869 - we found problematic to processing the injection points from within the module into the deployment. More investigation work is needed to get it properly working. For the LRA could be integrated as a extension we would propose a small workaround where the CDI can be asked to do injection programmatically during runtime.
