Description

I was tinkering an idea for debugging flaky tests, if we could attach brwoser side tracing with playwright?

then I found

  1. We already have it configured
  2. But it actually doesn't do anything, since 1. trace never stops to teardown 2. run-tests wipes out after run

PR adjusts the logics for the tracing

  1. Calls the context.tracing.stop when page closes or context is being closed
  2. Preserve files under test/traces under certain conditions - if it's in the CI, and it's retry, and the test is failed after retry

So we can download it and audit to get some more context to debug.

Closes PACK-2129

this should probably have been put in a different artifact as this artifact is being downloaded in CI for datadog and it will probably make the download a lot slower

but I guess it's only for failed tests which shouldn't happen on canary
