py-astroid: updated to 2.1.0

What's New in astroid 2.1.0?

* threading.Lock.acquire has the timeout parameter now.

* Pass parameters by keyword name when inferring sequences.

* Correct line numbering for f-strings for complex embedded expressions

  When a f-string contained a complex expression, such as an attribute access,
  we weren't cloning all the subtree of the f-string expression for attaching \ 
the correct
  line number. This problem is coming from the builtin AST parser which gives \ 
for the f-string
  and for its underlying elements the line number 1, but this is causing all \ 
sorts of bugs and
  problems in pylint, which expects correct line numbering.

* Add support for argparse.Namespace

* async functions are now inferred as AsyncGenerator when inferring their call \ 
result.

* Filter out Uninferable when inferring the call result result of a class with \ 
an uninferable __call__ method.

* Make compatible with AST changes in Python 3.8.

* Subscript inference (e.g. "a[i]") now pays attention to multiple \ 
inferred values for value
  (e.g. "a") and slice (e.g. "i")
