remove discoveryServiceUrl, update docs

[emdupre]

Closes #473.

Small documentation, build call updates for google-api-python-client usage. This is very much a first pass ; feedback welcome !

Awesome! Do you know if you can get tests to pass locally for this extractor?

i.e.:

pytest pliers/tests/extractors/api/test_google_extractors.py

I think you might have to add GOOGLE_APPLICATION_CREDENTIALS to your environment

Thanks ! I pushed a few updates on the tests that are necessary to match the new outputs.

Currently I'm still getting one failure:

Specifically, it's a 403 error on one of the test URLs:

FAILED pliers/tests/extractors/api/test_google_extractors.py::test_google_vision_api_label_extractor - urllib.error.HTTPError: HTTP Error 403: Forbidden

Do you have another URL that you'd recommend substituting here ?

I think I fixed your issue in the general test fix. Hopefully tests pass and we can merge!

[adelavega]

Tests passing! @emdupre can you confirm this is ready to merge?

[emdupre]

This is ready on my side, thanks !!!
