[feat]: Add system setting to enable/disable CQLSH basic console being displayed in UI

[millerjp]

Is your feature request related to a problem? Please describe. No

Describe the solution you'd like Have a system setting defaulting to false (i.e not displayed) on new installs to show/hide the basic CQLSH console and enable/disable the the toggle button

Additional context Once Enhanced CQLSH console is stable and feature complete, we will remove basic CQLSH console completely as an option from the UI - but I would not expect this to be the case to v 1.1+

@millerjp Now the basic cqlsh can be controlled via app's settings in the features section

Restarting the app is not required, and actually we can have active connections with basic cqlsh and others without it in the same app's session

Without basic cqlsh

With basic cqlsh
