[GitHub] [trafficcontrol] rob05c opened a new pull request, #6905: Add t3c metadata file

[GitBox <gi...@apache.org>]

rob05c opened a new pull request, #6905:
URL: https://github.com/apache/trafficcontrol/pull/6905

   Adds a t3c metadata file.
   
   Currently, this is just to help operational debugging. No behavior changes, other than writing the file.
   
   But a critical future feature this enables is deleting old files. Currently, t3c never deletes files, because it has no way of knowing what it dropped in the past, versus files in the ATS config directory places manually or by other tools. The metadata file tracks "owned" files, making it possible to safely delete old files. Though this PR doesn't add that.
   
   ## Which Traffic Control components are affected by this PR?
   - Traffic Control Cache Config (`t3c`, formerly ORT)
   
   ## What is the best way to verify this PR?
   Run t3c, verify a `t3c-apply-metadata.json` file is placed in the ATS config directory, with some useful information about the run.
   
   ## If this is a bugfix, which Traffic Control versions contained the bug?
   Not a bug fix.
