- move resource directory object into EddieEndpoint, including methods that use the resource directory (ip/port getters, discover_rd, publish/unpublish)
- access the resource directory using only coap requests even if the resource directory is local, without having to use direct method calls when the rd is in the same node.
- remove remove_endpoint and add_endpoint from ResourceDirectory because not necessary anymore
- move endpoints_to_string_list_filtered and rd_resources_to_string_list_filtered into private in ResourceDirectory
- adapt tests, eddie-endpoint, VirtualizationReceiver to the new changes
