Allow downstream firefox builds to self-select API keys to /country about classify-client HOT 3 CLOSED

For the regex pattern, it may be useful to have a way to communicate with the source of the requests. Perhaps we can consider the format being:

1. it's an email address, like: id:[email protected]
2. it's a TXT dns record, like id:firefox-location.somelinuxbuild.org <-- must resolve to an email address?

This would give us communicate with the source for some reason.

Requiring an email address or domain to be provided is good.

But I don't think we should/could have true validation. If downstream build is popular but we're unable to verify that record one day for whatever reason (maybe they moved domains), then that would leave existing users unable to hit the endpoint.

After speaking with @mostlygeek , we're going to stick with the original plan of using simple strings.
