Security fixes

- ``CurlAsyncHTTPClient`` now fully resets the curl object before reusing it. This prevents
  incorrectly reusing options from a previous request, specifically including client SSL and
  credentials used for accessing proxies. Thanks to `Koh Jun Sheng <https://github.com/seankohjs>`_
  for reporting this issue.
