Revert "Merge branch '27-modify-the-nunet-adapter-proto' into 'master'"

This reverts merge request !11 (merged) my bad @bulidiriba -- merged by mistake, since the extraction should be done on the service side, not on the adapter side as the adapter is generic. The way it should work is that the url is sent to the adapter-1, since adapter-1, then it is sent to fake_news_score, which is on the same machine as adapter-1, then the fake_news_score does the extraction and calls athene and uclnp as needed (the last part should already work and done by @Yitbarek, who can point to the exact lines of code)
