Legacy endpoint ids with '-' do not migrate cleanly

[Larisho]

This is a fix for the partially fixed legacy compatibility flag management.endpoints.migrate-legacy-ids. After the first fix, warnings were still issued when endpoint ids contained a hyphen. This bugfix extends the flag's effects to the hyphen as well as the previously implement dot. See #20703 and #18148 for more context around the issue.

@snicoll My pleasure; would love to do more.

Could you explain to me what forward port means with regards to the PR? Thanks

Gladly. This bug had to be fixed in the 2.2.x line so we first applied the fix there. We then merged the fix forward to 2.3.x and then master. We want to track the fact this bug was fixed in each release notes (2.2.10, 2.3.3 and 2.4.0-M2 respectively). We have a script that creates automatically an issue when we merge forward and the label is used to indicate this issue is only created for the purpose of tracking the change in a different feature release.

There is a bit more details on our wiki.
