feat(oohelperd): add prometheus metrics (#897)
Closes https://github.com/ooni/probe/issues/2183 While there, avoid exposing nil values for optional fields of the THResponse struct (i.e., "ip_info" and "tls_handshake"). While there, fix `measurexlite`'s `OperationLogger` test and make it deterministic rather than racy.
