This PR updates urllib3 from 1.25.3 to 1.25.10.

Changelog

1.25.9

-------------------

* Added ``InvalidProxyConfigurationWarning`` which is raised when
erroneously specifying an HTTPS proxy URL. urllib3 doesn't currently
support connecting to HTTPS proxies but will soon be able to
and we would like users to migrate properly without much breakage.

See `this GitHub issue <https://github.com/urllib3/urllib3/issues/1850>`_
for more information on how to fix your proxy config. (Pull 1851)

* Drain connection after ``PoolManager`` redirect (Pull 1817)

* Ensure ``load_verify_locations`` raises ``SSLError`` for all backends (Pull 1812)

* Rename ``VerifiedHTTPSConnection`` to ``HTTPSConnection`` (Pull 1805)

* Allow the CA certificate data to be passed as a string (Pull 1804)

* Raise ``ValueError`` if method contains control characters (Pull 1800)

* Add ``__repr__`` to ``Timeout`` (Pull 1795)

1.25.8

-------------------

* Drop support for EOL Python 3.4 (Pull 1774)

* Optimize _encode_invalid_chars (Pull 1787)

1.25.7

-------------------

* Preserve ``chunked`` parameter on retries (Pull 1715, Pull 1734)

* Allow unset ``SERVER_SOFTWARE`` in App Engine (Pull 1704, Issue 1470)

* Fix issue where URL fragment was sent within the request target. (Pull 1732)

* Fix issue where an empty query section in a URL would fail to parse. (Pull 1732)

* Remove TLS 1.3 support in SecureTransport due to Apple removing support (Pull 1703)

1.25.6

-------------------

* Fix issue where tilde (``~``) characters were incorrectly
percent-encoded in the path. (Pull 1692)

1.25.5

-------------------

* Add mitigation for BPO-37428 affecting Python <3.7.4 and OpenSSL 1.1.1+ which
caused certificate verification to be enabled when using ``cert_reqs=CERT_NONE``.
(Issue 1682)

1.25.4

-------------------

* Propagate Retry-After header settings to subsequent retries. (Pull 1607)

* Fix edge case where Retry-After header was still respected even when
explicitly opted out of. (Pull 1607)

* Remove dependency on ``rfc3986`` for URL parsing.

* Fix issue where URLs containing invalid characters within ``Url.auth`` would
raise an exception instead of percent-encoding those characters.

* Add support for ``HTTPResponse.auto_close = False`` which makes HTTP responses
work well with BufferedReaders and other ``io`` module features. (Pull 1652)

* Percent-encode invalid characters in URL for ``HTTPConnectionPool.request()`` (Pull 1673)
