feat(users/Profpatsch/whatcd-resolver): trace http requests r/7766
Move the http calls into their own module, so we can trace the request and provide a simple copy-to-replay command. We have to work around a bug in the otel library, which would limit our attribute value length to 128 bytes because it uses the wrong option value. ~~~ `ifExists` is finally made more useful for dealing with optional attributes in e.g. lists.
