Uninstall containers using force remove

[pipex]

When uninstalling a container for a restart from the API on when moving between releases, this prefers to force remove the container rather than stop then remove. This has the same effect in the end, but force remove is an atomic call, meaning if the supervisor is killed between the stop and remove, the engine will proceed with the operation and the supervisor will know to recover from the target state after the restart.

This is not the right solution, force remove uses SIGKILL instead of sigterm

docker rm --help                                                                                                           dynamic-sensors
