Changelog: Feature: Cache HTTP request sessions between API calls
Docs: TODO

Avoid creating a new session for each ConanRequester instance, this helps a lot with performance, as it avoids the overhead duplicate handshakes

I get an additional 40% speedup on top of #17449

We need to design, implement and document properly the "invalidating" and reloading of global.conf, like the requester will not get new conf after a config install. I think this is perfectly good as default, but the "invalidation" should also be doable and documented. I'll create a ticket for this later.

The _max_retries is now legacy?
