Add async/await support

mwilliammyers commented 3 years ago

This is a draft PR because, although it is fairly usable in its current state (see google-apis-rs/generated@refactor/async), it has some missing functionality:

[ ] [Google Cloud Storage] refactor ResumableUpload to be async (ie update google_rest_api_generator/gen_include/resumable_upload.rs to support async/await)
[ ] [various; anything that supports response pagination?] implement Stream instead of Iter so it is async (ie replace google_rest_api_generator/gen_include/iter.rs).

The above items correspond to FIXME comments in the code.

What is the state of this pull request? I would like to use it.

On my fork I changed to

reqwest = { version = "0.11.2", default-features = false, features = ["json"] }

to get the latest tokio. Seems to work pretty well for me so far. No other changes were needed.
