This library parses GitHub CODEOWNERS syntax and makes the owners
available within the code for programmatic usage.

Correlate the test scenarios with the GitHub teams that own these test
scenarios, so that we can pretty-print some helpful assistance to
developers in CI when a test fails.

The intent here is that this makes the developer experience easier by
connecting developers who are struggling with a CI failure with the
owners of those tests.

When reporting owners of test files as part of the --log-codeowners
parameter, autodetect the workflow file from the environment variable
GITHUB_WORKFLOW_REF which GitHub sets in the environment in order to
list the owners for the workflow itself while listing owners for a
failed test.

This tool takes JSON output as presented by 'go test -json ...' on stdin
and outputs a table with the failed tests and any corresponding owners.

Example usage:

  $ go test -json ./test/fail/ | go run ./tools/testowners/
  ⛑️ The following owners are responsible for reliability of the failing test(s):
  Package                              Owner
  github.com/cilium/cilium/test/fail   @cilium/ci-structure

LOG_CODEOWNERS=1 will log the codeowners corresponding to a unit test
failure when the Makefile hands unit test output to its GOTEST
formatters.

Example (with tparse installed):

$ LOG_CODEOWNERS=1 TESTPKGS=./pkg/policy make tests-privileged
  CHECK   running privileged tests...
