GSK-1365 Make websocket reactive to worker status

This is an improvement of GSK-1199.

Currently, the socket is sending the worker status as a polling system. The idea is to only send the status message in two conditions:

1- if status changed from connected to disconnected and vice-versa;

2- if there is a new subscriber to the websocket channel
