[DAC] - Add commands for running in different modes

Context

Follows !7506 (merged) - This MR adds commands to configure the DAC node in any of the 4 possible modes of operation. The only mode in which the DAC node can run is currently the legacy mode. Tezts have been refactored to use the new set of commands
