Upgrade to axum ^0.7

[lebenitza]

Are there any plans to migrate to axum v0.7.x ?

https://github.com/tokio-rs/axum/releases/tag/axum-v0.7.0

This comes with other dependencies that need to be upgraded too, mentioned in the 0.7.0 release. I tried figuring this out but I am stuck at

Hi @lebenitza ,
Sorry for the delay. I think it makes sense to update it. Would you like to contribute a PR? I'm happy to support you if you need help.

I taking a quick look at what it would take to do this, and it seems that upgrading to http ^1.0 is unavoidable.
For example, I can't find a good way to create an http 1.1.0 response from an http 0.2.12 response to implement IntoResponse for Event.

Is that what you would expect, @Lazzaretti ?

[Lazzaretti]

I think you are right, the http crate has to be updated. If this is the case, I'm fine with an upgrade.

Sounds good. I have some travel scheduled, but I can take this up in a few weeks if no one else has by then.
