Update dependency versions

We're using google api client and we cannot use this old one, and having two versions of the same jar makes lots of troubles here. 

So I moved the google https client dependency to the latest one. Also the other dependencies were updated as well as upgraded to version to `1.8.0-SNAPSHOT` as I removed the deprecated getResponse. Not all tests are passing, but exactly the same fail which fail before the change ;)

Would you mind to deploy this to maven repo as fast as possible :) ?

Let me know if I can help you to push this out!
