High Volume Mode

If the callcenter is in a high volume mode (boolean), the chatbot should display appropriate messages to the customer.
This might be based on automated information (SLA, waiting time, nbr of available agents)
or
based on a Supervisor setting a manual state.
The suggestion is to enable a supervisor to set the state manually, and the chatbot to act appropriately (for ex, play a certain message). To be implemented by @rabi.haider with @ehtasham.malik as a Chatbot script.

Estimate: 4 days (5 days with a GUI for the supervisor to toggle ON/ OFF)
