IETF RFC 3986 classifies "~" as a reserved character [1], however until python3.7 [2], python's url parsing used to encode this character. urllib has seen a lot of churn in various python releases, and hence we were using a six wrapper to shield ourselves, however, this backwards-incompatible change in encoding norms forces us to deal with the problem at our end. Cinder's API accepts "~" in both, its encoded or un-encoded forms. So, let's stop encoding it within cinderclient, regardless of the version of python running it. Also fix an inconsitency around the use of the generic helper method in utils added in I3a3ae90cc6011d1aa0cc39db4329d9bc08801904 (cinderclient/utils.py - build_query_param) to allow for False as a value in the query.
