Support loading a custom TLS server name from kubeconfig

[multani]

This honors the tls-server-name parameter which can be present in a kubeconfig configuration file.

The implementation is similar to the one done in kubernetes-client/python#1933

This needs a released version of aio-libs/aiohttp#7541 This is implemented in aiohttp v3.9.0.

Fix: #267

@tomplus could you take a look at this pull request preemptively?

I'm still waiting for an official release of aiohttp containing aio-libs/aiohttp#7541 and until then, I'm not going to turn this pull request into an official one (the tests are not passing because of this).

But it would be nice to get a first overview on the general approach, in particular the patch post-client generation.

@multani Thanks. It looks good to me. If you have time you can also create a PR to openapi-generator, it helps us to remove the patch in the feature (https://github.com/OpenAPITools/openapi-generator/blob/master/modules/openapi-generator/src/main/resources/python/asyncio/rest.mustache).

@tomplus Thanks, that was exactly the kind of feedback I was looking for :)

I'll make the pull request there as well then!

edit: it's there as a draft too: OpenAPITools/openapi-generator#16380
