Work out how to contact bandwidth scanner operators

See #30196 (moved).

We currently have two competing proposed headers:

• an email address
• an unstructured ContactInfo text field

For quick diagnosis of problems, it would be great if the bandwidth scanners added some contact information to the output. We are planning to add contact strings to exit scanners.

Let's not specify another unstructured contact string, please.

Instead, if we need to email someone, let's specify an operator email address.

• The need for the inline contact information becomes evident when we look at how much trouble we've had tracking down who runs the default bridges in Tor Browser #30121 (moved)

Do we need contact information ... initially knowing who runs the scanners (usually the same dirauth)?.
