both WildFly ejb3 subsystem and metadata-ejb contain an enum to represent the types of ejb method invocations:

org.jboss.metadata.ejb.spec.MethodInterfaceType:

public enum MethodInterfaceType {
    Home,
    Remote,
    LocalHome,
    Local,
    ServiceEndpoint,
    Timer,
    MessageEndpoint
}

org.jboss.as.ejb3.component.MethodIntf:

public enum MethodIntf {
    BEAN, // represents a direct call to the Jakarta Enterprise Beans (temporary)
    HOME,
    REMOTE,
    LOCAL_HOME,
    LOCAL,
    SERVICE_ENDPOINT,
    TIMER,
    MESSAGE_ENDPOINT,
}

ejb3 subsystem's enum has one more value: BEAN to represent the a default, direct invocation.

We should be able to merge the 2 enums, and remove all the code that convert between one to the other.
