Limit traceback to one entry by default

See original GitHub issue

What’s the problem this feature will solve?

Large and unnecessary tracebacks in user bug-reports

Describe the solution you’d like

Set the trace-back limit sys.tracebacklimit to 1 by default. Don’t set when verbose-logging (ie -vv passed at command-line). This includes build-backend subprocesses (in the vendored pep517 subprocess), but not when using an in-tree build-backend.

I don’t think they are unnecessary by any means. And, making the build-backend process fail gracefully is the responsibility of the build backend – pip shouldn’t be trying to cooerce their output to be shorter and potentially make it more difficult for the authors to diagnose issues.

FWIW, I do agree that we should be presenting our internal errors differently though. Something like rich’s tracebacks could make sense for that. I have a draft patch somewhere, adding rich tracebacks and a PIP_RICH_TRACEBACKS=0, pip --no-rich-tracebacks.
