    Stop encoding "~" in query parameters

    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.

    Manila's API accepts "~" in both, its encoded
    or un-encoded forms. So, let's stop encoding it
    within manilaclient, regardless of the version
    of python running it.
