Buildkit containers should stop running automatically after an image has been successfully built

[Danyal-Faheem]

Hi, I wanted to request a feature where buildkit containers should stop running after an image has been built successfully.

For example, I use a specific builder context and then I run a docker build command. Docker notices that the buildkit container is stopped so it starts it up. However, after the image has finished building, the container is still running in the background which is potentially eating up valuable resources.

I wanted to request that the container should be stopped as it is automatically restarted whenever another docker build command is run so it will have no effect whatsoever on the actual usage of buildkit, except maybe adding a few seconds to start the container, but will improve the user experience overall.

Thank you in advance if someone decides to implement this.
