Resolve "Stop container if DMS is killed"

Description

1. Watcher Mechanism:

   • Introduced a watcher mechanism that continuously monitors the heartbeat of the main DMS.
   • The watcher initiates cleanup if no heartbeat from the DMS is received for a specified timeout.

2. Communication via Local Socket:

   • Established a local TCP socket communication on localhost:9898 between the main DMS and the watcher.
   • The main DMS sends heartbeat signals to the watcher through this socket.

3. Container Cleanup:

   • Used the Docker SDK to interact with Docker and manage containers.
   • Containers with a specific naming convention (DMS_...) are targeted for cleanup.
   • When a cleanup is initiated, the watcher stops and removes the containers following the naming convention.

Checklist
