Update input/output of Spec11 pipeline to final format

This changes the BigQuery input to the fields we ultimately want (fqdn,
registrarName, registrarEmailAddress) and the output to a structured POJO
holding the results from the API. This POJO is then converted to its final text output, i.e.:

Map from registrar e-mail to list of threat-detected subdomains:
{"registrarEmail": "c@fake.com", "threats": [{"url": "a.com", "threatType": "MALWARE"}]}
{"registrarEmail": "d@fake.com", "threats": [{"url": "x.com", "threatType": "MALWARE"}, {"url": "y.com", "threatType": "MALWARE"}]}

This gives us all the data we want in a JSON structured format, to be acted upon downstream by the to-be-constructed PublishSpec11ReportAction. Ideally, we would send an e-mail directly from the beam pipeline, but this is only possible through third-party providers (as opposed to app engine itself).
