[server] Disable tracing errors

[geropl]

Description

• server: don't use FOLLOWS_FROM references
• replace references by manually enriching spans for websocket notifications
• set JAEGER_DISABLED when tracing is not configured explicitly to avoid noisy error messages (for SH case, for example)

How to test

• as with-observability is not working atm:
  • kubectl logs server-79dfdf9bbd-f6fmn server -f
  • start a workspace
  • note that the server logs do not contain any tracing-related errors/warnings

with-observability does not work at the moment, so we test the tracing changes in server by starting a workspace, which shows there are no errors (without checking the actual structure in honeycomb).
