prior to this change, the schema does not allow newer
cipher suites, and the default ciperhs given in the conf file
is likely not supported by some clients (which only supports dtls v1.2)
* fix(rule): reformat some code for rule-engine
* fix(lwm2m): change publish_update_when to publish_update_msg_when
Change the option name publish_update_when -> publish_update_msg_when.
Also change the object_list_changed to contains_object_list, as the
the later describes the default behavior correctly.
* fix(lwm2m): publish_update_msg_when -> update_msg_publish_condition
