Update webargs to 5.0.0

[pyup-bot]

This PR updates webargs from 4.3.1 to 5.0.0.

Changelog

5.0.0

******************

Features:

* *Backwards-incompatible*: A 400 HTTPError is raised when an
invalid JSON payload is passed.  (:issue:`329`).
Thanks :user:`zedrdave` for reporting.

Other changes:

* Backwards-incompatible*: `webargs.argmap2schema` is removed. Use
`webargs.dict2schema` instead.
* *Backwards-incompatible*: `webargs.ValidationError` is removed.
Use `marshmallow.ValidationError` instead.


.. code-block:: python

  <5.0.0
 from webargs import ValidationError


 def auth_validator(value):
      ...
     raise ValidationError("Authentication failed", status_code=401)


 use_args({"auth": fields.Field(validate=auth_validator)})
 def auth_view(args):
     return jsonify(args)


  >=5.0.0
 from marshmallow import ValidationError


 def auth_validator(value):
      ...
     raise ValidationError("Authentication failed")


 use_args({"auth": fields.Field(validate=auth_validator)}, error_status_code=401)
 def auth_view(args):
     return jsonify(args)


* *Backwards-incompatible*: Missing arguments will no longer be filled
in when using ``use_kwargs`` (:issue:`342,307,252`). Use ``**kwargs``
to account for non-required fields.

.. code-block:: python

  <5.0.0
 use_kwargs(
     {"first_name": fields.Str(required=True), "last_name": fields.Str(required=False)}
 )
 def myview(first_name, last_name):
      last_name is webargs.missing if it's missing from the request
     return {"first_name": first_name}


  >=5.0.0
 use_kwargs(
     {"first_name": fields.Str(required=True), "last_name": fields.Str(required=False)}
 )
 def myview(first_name, **kwargs):
      last_name will not be in kwargs if it's missing from the request
     return {"first_name": first_name}


* `simplejson <https://pypi.org/project/simplejson/>`_ is now a required
dependency on Python 2 (:pr:`334`).
This ensures consistency of behavior across Python 2 and 3.

4.4.1

******************

Bug fixes:

* Remove usages of ``argmap2schema`` from ``fields.Nested``,
``AsyncParser``, and ``PyramidParser``.

4.4.0

******************

* *Deprecation*: ``argmap2schema`` is deprecated in favor of
``dict2schema`` (:pr:`352`).
