Incorrect use of ReloadRequiredWriteAttributeHandler for host resources

ReloadRequiredWriteAttributeHandler inherits the default behavior of AbstractWriteAttributeHandler.requiresRuntime(), which is to only process Stage.RUNTIME if context.isNormalServer(). So any use in host resources needs to override that behavior. This isn't done in at least some places. See https://bugzilla.redhat.com/show_bug.cgi?id=1085228 for an example.
