[REQ] Improve uniqueness of progress group logs

[invidian]

What kind of request is this?

Improvement of existing experience

What is your request or suggestion?

Right now when building e.g. a DEB container, the progress groups which are being printed are not very informative because they are not unique. Output may look like below, especially on consecutive builds with caching:

Perhaps things like Build deb package or Prepare debian sources could be enhanced with more specific information?

Are you willing to submit PRs to contribute to this feature request?

• Yes, I am willing to implement it.

Yes, thank you I've been meaning to open this issue.
It works great in the custom UI we use internally, but the docker CLI's TTY output its really bad.

[cpuguy83]

The thing here is the progress groups are a hierarchy and docker's TTY output does not show that.

[cpuguy83]

Oh! Some of this may be that there are some places where we explicitly unlazy the build.
I'm working on removing that (which breaks the DAP debugger anyway).
