Provide a hosting and define protocol to integrate with DSC-V3.

[BerheAbrha]

Summary of the new feature / enhancement

• Today dsc-v3 only supports calling it from command line. Other agents/ local services that need to call it, - Will need to spawn a new DSC process for every request with command line arguments (no worker management) - be in charge of lifetime of the dsc process (stop/start).

Proposed technical implementation details (optional)

• Implement a local service that hosts DSC
• Define protocol to interact with it.
