Extend showing substeps to further endpoints

[szaimen]

We could maybe also show sub-steps for stopping containers, starting backup container and restore and others.

endpoints:

• /api/docker/start aio-interface: show sub-steps for starting containers #7458
  • /api/docker/watchtower Dockercontroller: refactor streaming responses into dedicated functions and use them in StartWatchtowerContainer method #7674
  • /api/docker/backup-check DockerController: refactor StartBackupContainerCheck to show the starting state #7675
  • /api/docker/backup-list DockerController: refactor StartBackupContainerList to show the starting state #7723
  • /api/docker/backup-check-repair DockerController: refactor StartBackupContainerCheckRepair show the starting state #7724
  • /api/docker/getwatchtower (doesnt make sense)
• /api/docker/stop DockerController: refactor stopping of containers to show the current process #7676
  • /api/docker/backup DockerController: refactor StartBackupContainerBackup to show the stopping and starting state #7705
  • /api/docker/restore DockerController: refactor StartBackupContainerRestore to show the stopping and starting state #7721
  • /api/docker/backup-test DockerController: refactor StartBackupContainerTest to show the stopping and starting state #7722
• /api/docker/logs (doesnt make sense)
