[PyUP] Update requests to 2.27.1

[pyup-bot]

This PR updates requests from 2.18.4 to 2.27.1.

Changelog

2.27.0

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

**Improvements**

- Officially added support for Python 3.10. (5928)

- Added a `requests.exceptions.JSONDecodeError` to unify JSON exceptions between
Python 2 and 3. This gets raised in the `response.json()` method, and is
backwards compatible as it inherits from previously thrown exceptions.
Can be caught from `requests.exceptions.RequestException` as well. (5856)

- Improved error text for misnamed `InvalidSchema` and `MissingSchema`
exceptions. This is a temporary fix until exceptions can be renamed
(Schema->Scheme). (6017)

- Improved proxy parsing for proxy URLs missing a scheme. This will address
recent changes to `urlparse` in Python 3.9+. (5917)

**Bugfixes**

- Fixed defect in `extract_zipped_paths` which could result in an infinite loop
for some paths. (5851)

- Fixed handling for `AttributeError` when calculating length of files obtained
by `Tarfile.extractfile()`. (5239)

- Fixed urllib3 exception leak, wrapping `urllib3.exceptions.InvalidHeader` with
`requests.exceptions.InvalidHeader`. (5914)

- Fixed bug where two Host headers were sent for chunked requests. (5391)

- Fixed regression in Requests 2.26.0 where `Proxy-Authorization` was
incorrectly stripped from all requests sent with `Session.send`. (5924)

- Fixed performance regression in 2.26.0 for hosts with a large number of
proxies available in the environment. (5924)

- Fixed idna exception leak, wrapping `UnicodeError` with
`requests.exceptions.InvalidURL` for URLs with a leading dot (.) in the
domain. (5414)

**Deprecations**

- Requests support for Python 2.7 and 3.6 will be ending in 2022. While we
don't have exact dates, Requests 2.27.x is likely to be the last release
series providing support.

2.26.0

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

**Improvements**

- Requests now supports Brotli compression, if either the `brotli` or
`brotlicffi` package is installed. (5783)

- `Session.send` now correctly resolves proxy configurations from both
the Session and Request. Behavior now matches `Session.request`. (5681)

**Bugfixes**

- Fixed a race condition in zip extraction when using Requests in parallel
from zip archive. (5707)

**Dependencies**

- Instead of `chardet`, use the MIT-licensed `charset_normalizer` for Python3
to remove license ambiguity for projects bundling requests. If `chardet`
is already installed on your machine it will be used instead of `charset_normalizer`
to keep backwards compatibility. (5797)

You can also install `chardet` while installing requests by
specifying `[use_chardet_on_py3]` extra as follows:

 shell
 pip install "requests[use_chardet_on_py3]"
 

Python2 still depends upon the `chardet` module.

- Requests now supports `idna` 3.x on Python 3. `idna` 2.x will continue to
be used on Python 2 installations. (5711)

**Deprecations**

- The `requests[security]` extra has been converted to a no-op install.
PyOpenSSL is no longer the recommended secure option for Requests. (5867)

- Requests has officially dropped support for Python 3.5. (5867)

2.25.1

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

**Bugfixes**

- Requests now treats `application/json` as `utf8` by default. Resolving
inconsistencies between `r.text` and `r.json` output. (5673)

**Dependencies**

- Requests now supports chardet v4.x.

2.25.0

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

**Improvements**

- Added support for NETRC environment variable. (5643)

**Dependencies**

- Requests now supports urllib3 v1.26.

**Deprecations**

- Requests v2.25.x will be the last release series with support for Python 3.5.
- The `requests[security]` extra is officially deprecated and will be removed
in Requests v2.26.0.

2.24.0

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

**Improvements**

- pyOpenSSL TLS implementation is now only used if Python
either doesn't have an `ssl` module or doesn't support
SNI. Previously pyOpenSSL was unconditionally used if available.
This applies even if pyOpenSSL is installed via the
`requests[security]` extra (5443)

- Redirect resolution should now only occur when
`allow_redirects` is True. (5492)

- No longer perform unnecessary Content-Length calculation for
requests that won't use it. (5496)

2.23.0

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

**Improvements**

- Remove defunct reference to `prefetch` in Session `__attrs__` (5110)

**Bugfixes**

- Requests no longer outputs password in basic auth usage warning. (5099)

**Dependencies**

- Pinning for `chardet` and `idna` now uses major version instead of minor.
This hopefully reduces the need for releases every time a dependency is updated.

2.22.0

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

**Dependencies**

- Requests now supports urllib3 v1.25.2.
(note: 1.25.0 and 1.25.1 are incompatible)

**Deprecations**

- Requests has officially stopped support for Python 3.4.

2.21.0

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

**Dependencies**

- Requests now supports idna v2.8.

2.20.1

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

**Bugfixes**

- Fixed bug with unintended Authorization header stripping for
redirects using default ports (http/80, https/443).

2.20.0

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

**Bugfixes**

-   Content-Type header parsing is now case-insensitive (e.g.
 charset=utf8 v Charset=utf8).
-   Fixed exception leak where certain redirect urls would raise
 uncaught urllib3 exceptions.
-   Requests removes Authorization header from requests redirected
 from https to http on the same hostname. (CVE-2018-18074)
-   `should_bypass_proxies` now handles URIs without hostnames (e.g.
 files).

**Dependencies**

- Requests now supports urllib3 v1.24.

**Deprecations**

- Requests has officially stopped support for Python 2.6.

2.19.1

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

**Bugfixes**

-   Fixed issue where status\_codes.py's `init` function failed trying
 to append to a `__doc__` value of `None`.

2.19.0

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

**Improvements**

-   Warn user about possible slowdown when using cryptography version
 < 1.3.4
-   Check for invalid host in proxy URL, before forwarding request to
 adapter.
-   Fragments are now properly maintained across redirects. (RFC7231
 7.1.2)
-   Removed use of cgi module to expedite library load time.
-   Added support for SHA-256 and SHA-512 digest auth algorithms.
-   Minor performance improvement to `Request.content`.
-   Migrate to using collections.abc for 3.7 compatibility.

**Bugfixes**

-   Parsing empty `Link` headers with `parse_header_links()` no longer
 return one bogus entry.
-   Fixed issue where loading the default certificate bundle from a zip
 archive would raise an `IOError`.
-   Fixed issue with unexpected `ImportError` on windows system which do
 not support `winreg` module.
-   DNS resolution in proxy bypass no longer includes the username and
 password in the request. This also fixes the issue of DNS queries
 failing on macOS.
-   Properly normalize adapter prefixes for url comparison.
-   Passing `None` as a file pointer to the `files` param no longer
 raises an exception.
-   Calling `copy` on a `RequestsCookieJar` will now preserve the cookie
 policy correctly.

**Dependencies**

-   We now support idna v2.7.
-   We now support urllib3 v1.23.
