CoAP

Before merging v2 into the master, the following points shall be resolved.

Renaming:
groupID -> resourceServerID
deviceID -> resourceServerID
aggregateID -> resourceID

• rename handle to aggregateEvents in aggrModel

Additionally, get rid of debug logs printing command execution times. We will use open telemetry for this.

We are developing a little demo but lobarocoap can't parse a response with no options. it fails of the following code in /src/coap_options.c

if (srcArr[0] == OPTION_PAYLOAD_MARKER) {
		INFO("- Options must not start with payload marker!\r\n");
		return COAP_PARSE_MESSAGE_FORMAT_ERROR;
}

Other clients like libcoap or coapthon or java libraries have no problem with the packets. And

All activities and triggers need to be reviewed, documented and readme updates.
