Unexpected behaviour of .delay

[electronick1]

Before job added to the queue, we executing adv_bind_arguments here

If processor has **kwargs defined inside, all data will be lost and "Argument missing" error will be raised. This is example of adv_bind_arguments behaviour with **kwargs function:

from sqs_workers.utils import adv_bind_arguments

def wrapper_func(*args, **kwargs):
     def func(a):
           print(a)
     func(*args, **kwargs)
     print(args, kwargs)

adv_bind_arguments(wrapper_func, [], dict(a=1))
# pring result: {'args': (), 'kwargs': {}}

As you can see a=1 is lost and "Argument missing" error will be raise when processor will try to execute this job.
This is especially critical when you want to decorate your sqs processor, because you should have *args, **kwargs statement inside a decorator.

I can confirm that the problem exists, but there's no easy way to fix it quickly without rewriting Werkzeug's bind_arguments:

>>> from werkzeug.utils import bind_arguments
>>> def foo(a, b): pass
...
>>> bind_arguments(foo, (), {"a": 1, "b": 2})
{'a': 1, 'b': 2}
>>> def foo_kwargs(**kwargs): pass
...
>>> bind_arguments(foo_kwargs, (), {"a": 1, "b": 2})
{'kwargs': {}}

As you can see, the output for the function that accepts kwargs doesn't make any sense.

Patches or documentation updates with a workaround are welcome
