* Offchain worker: Enable http2 and improve logging

Apparently some webpages now return http2 by default and that silently breaks the offchain http
extension. The solution to this is to enable the `http2` feature of hyper. Besides that, this pr
improves the logging to make it easier to debug such errors.

* FMT

* Adds http2 test

Bumps [tokio](https://github.com/tokio-rs/tokio) from 1.12.0 to 1.13.0.

* WIP: bump changes crates since v3 tag to next breaking

cargo unleash version bump-breaking --changed-since v3.0.0
cargo unleash version set-pre dev --changed-since v3.0.0

specifying a `CARGO_TARGET_DIR` will help

* fixup: Ensure the temp target dir exists for unleash check

* Bump pallet-transaction-payment-rpc-runtime-api as well

Needed for Polkadot

* Bump pallet-transaction-payment-rpc as well

Needed for Polkadot
