    py-ipython: updated to 7.17.0

    IPython 7.17
    ============

    IPython 7.17 brings a couple of new improvements to API and a couple of user
    facing changes to make the terminal experience more user friendly.

    :ghpull:`12407` introduces the ability to pass extra argument to the IPython
    debugger class; this is to help a new project from ``kmaork``
    (https://github.com/kmaork/madbg) to feature a fully remote debugger.

    :ghpull:`12410` finally remove support for 3.6, while the codebase is still
    technically compatible; IPython will not install on Python 3.6.

    lots of work on the debugger and hidden frames from ``@impact27`` in
    :ghpull:`12437`, :ghpull:`12445`, :ghpull:`12460` and in particular
    :ghpull:`12453` which make the debug magic more robust at handling spaces.

    Biggest API addition is code transformation which is done before code execution;
    IPython allows a number of hooks to catch non-valid Python syntax (magic, prompt
    stripping...etc). Transformers are usually called many time; typically:

     - When trying to figure out whether the code is complete and valid (should we
       insert a new line or execute ?)
     - During actual code execution pass before giving the code to Python's
       ``exec``.

    This lead to issues when transformer might have had side effects; or do external
    queries. Starting with IPython 7.17 you can expect your transformer to be called
    less time.

    Input transformers are now called only once in the execution path of
    `InteractiveShell`, allowing to register transformer that potentially have side
    effects (note that this is not recommended). Internal methods `should_run_async`, and
    `run_cell_async` now take a recommended optional `transformed_cell`, and
    `preprocessing_exc_tuple` parameters that will become mandatory at some point in
    the future; that is to say cells need to be explicitly transformed to be valid
    Python syntax ahead of trying to run them. :ghpull:`12440`;

    ``input_transformers`` can now also have an attribute ``has_side_effects`` set
    to `True`, when this attribute is present; this  will prevent the transformers
    from being ran when IPython is trying to guess whether the user input is
    complete. Note that this may means you will need to explicitly execute in some
    case where your transformations are now not ran; but will not affect users with
    no custom extensions.
