[py] Check the values in NO_PROXY and set the poolmanager accordingly

If people are setting no_proxy for certain values to get around the need
to have a proxy for localhost, mostly, then we should set the poolmanager
to proxymanager if not in no_proxy or poolmanager if it is.

Fixes #9925
Fixes #9967
