Add HTTPX transport

[helderco]

Fixes #154

This is an alternative to #340.

Notes

• Both sync and async transports
• File upload support (but no stream or AsyncGenerator)
• Docs
• Sync tests based on requests tests
• Async tests based on aiohttp tests
• The other transports log the query and result in info but I think it makes more sense for debug

It's because of this issue.
As a workaround, you can run pip install jinja2==3.0 and it should work.
I'll upgrade sphinx in a separate PR to fix this cleanly.

Thanks, I was able to run locally and fixes already sent!

Please add the following changes:

• add httpx dependencies in docs/intro.rst
• add httpx link in docs/usage/file_upload.rst
• add a file in docs/modules for httpx and add it to docs/modules/gql.rst This should fix the non-working ref in the doc

Please don't use force-push but instead push a normal commit so that we can see the changes more easily.

[helderco]

Do I add the gql-with-httpx to conda instructions in intro.rst? Where are those created?

Got it, but fyi, in Github you can see what changed with these buttons:

At dagger we amend a lot to keep the history clean.

In another repository.
Maybe don't add it right now, I'll add it later with the next stable version of gql.

I'm not a fan of force-pushing except in very rare occurrences.
The commits here are squashed anyway when we merge so the main history will still stay clean 😄

[helderco]

Thanks for the quick review and merge! 🎉

[leszekhanusz]

Thanks for the quick review and merge! tada

And thank you again for your help!

[prabhu]

Any ideas when this would be released?

[leszekhanusz]

@prabhu it's already released in a pre-release: v3.5.0b0

[prabhu]

Thanks @leszekhanusz. Will wait for the final release.
