Add timing metrics to non-debug output #17
Description
When trying to test the efficacy of layer caching and trying to make optimizations around the same, it's currently necessary to view the raw logs of the action output. This is both tedious and somewhat difficult to follow due to the log formatting.
What I'd like to see:
- During pull, display the duration and size of each successfully-pulled image
- After pull, show total duration
- After each build step, include duration
- After each build step, show image size
Also, on the same thread, it'd be nice to suppress the exec data if possible. This may be tied to the implementation of that tool though. And it should in general respect the quiet setting.
