Remove ssl_support.

[jaraco]

Fixes #2715.

It appears that ssl.match_hostname has been deprecated since Python 3.7 and without any replacement. Perhaps that means that hostname verification is built into the default URL openers, or maybe it means the functionality isn't supported any longer. In either case, since the Setuptools package index code is deprecated, there's no point in trying to drag this functionality into the future, so just rely on what on the default implementation for HTTPS connections.

Thoughts about replacement for find_ca_bundle

Dear Jason,

at crate/crate-python#523 (comment), we discovered setuptools dropped the setuptools.ssl_support module.

We have been using setuptools.ssl_support.find_ca_bundle within our test suite, which croaks like ¹ when using a more recent version of setuptools.

Maybe you have any sort of suggestion how to resolve that, other than vendoring the previous version of the setuptools.ssl_support module into the failing testsuite?

With kind regards,
Andreas.
