After starting to use poetry to properly resolve airflow dependencies I faced network issues that I pinpointed to httplib2 interactions with proxy in my corporate network.
When making an http request I would get a "Network not reachable" exception
I isolated the problem to happen when using a very old version of httplib2 while using gcp extra which has a dependency range too strict (~=0.9.2)
I noticed that this dependency used to be httplib2>=0.9.2 and it was changed as part of
AIRFLOW-3971 commit (91b856f) without a clear reason why a more strict dependency is needed
