Upgrade networking stack dependencies

[kKdH]

There is a new version of axum (our web application framework), we would like to update to. The update relates also to hyper, http, and reqwest which should be updated too. Due to several breaking changes the update is more complex.

[mbfm]

It looks like most conflicts happen, because the reqwest library isn't yet ready for using hyper and http 1.0: seanmonstar/reqwest#2039

Trying to upgrade axum or hyper individually, forces those to use a new version of the http library, incompatible with what reqwest supports (0.2).

[mbfm]

The tonic library is not yet ready either: hyperium/tonic#1579

[mbfm]

reqwest is now ready for upgrade, but tonic is still not ready.

A partial upgrade still fails due to two different versions of the http crate (0.2.12 and 1.1.0) being pulled in as dependencies.

[mbfm]

tonic is now also ready, as of version 0.12.0: https://github.com/hyperium/tonic/releases/tag/v0.12.0

[mbfm]

Upgrade attempted on branch issue-29-hyper-http-upgrade.

OpenTelemetry still seems to not be ready: open-telemetry/opentelemetry-rust#1674

[mbfm]

OpenTelemetry is ready, now waiting for tracing-opentelemetry: tokio-rs/tracing-opentelemetry#154

[mbfm]

tracing-opentelemetry is ready. Struggling with upgrading Axum for our gRPC+HTTP backend. The relevant example has not been updated yet, so might not yet be easily possible: https://github.com/tokio-rs/axum/blob/main/examples/rest-grpc-multiplex/src/main.rs

[mbfm]

reqwest-retry depends on the instant library which had an advisory issued, due to being unmaintained. We cannot upgrade reqwest-retry due to this issue.

Implemented in 4e8c2e1 and following commits.
