Add support for classifying invalid compatibility reports to the http service

[ksy36]

There will be a scheduled ETL job with https://github.com/mozilla/docker-etl that should populate a batch of reports from BQ and submit a POST request for classification for them. An example request will likely look as follows:

[
   {
        "uuid": "954dbc23-91e6-4d6f-a10a-405f46663e31",
        "title": "https://www.threads.net/t/CuRtcYTNY3J",
        "body": "Loads blank page."
    },
   {
        "uuid": "af7e27b5-3ce3-46e1-8294-5baea36782cc",
        "title": "https://play.google.ocm/",
        "body": "Can\u0027t open the site"
    }
