feat: update docker images (#243)

* 1. prevent changing property.json anywhere
2. every worker start will have a new property.json, strip property.json with non-use graphs
3. except for channel name, token and asr_language, move all other
   properties settings to frontend

* 1. moved properties to frontend
2. frontend can now overwrite property values, while channelName,
   remoteStreamUid still takes highest priority
3. use process group to better kill worker

* fix: remove legacy graph mappings

* fix: use native strings.Join

* fix: add page description

* feat: update images to latest
