GeocodeFarm is the only geocoder which tests constantly fail due to the service availability issues. I have observed:

• A week-long expired TLS certificate
• Sporadic "No results" errors (8ce18b1)
• Intermittent connection refused errors

In fact, this is the only service for which I had to add an environment variable to allow quickly disabling tests without a commit: a6af73a. And I occasionally have to switch on that env to make the test suite pass.

The current issue is that along with "connection refused" errors the service returns an inadequate address value: #437

I believe that level of service is inappropriate for a public API, so I'm considering removing GeocodeFarm geocoder in geopy 2.2, to avoid anyone wasting their time on a service which is that unstable.
