[pbs-devel] [RFC proxmox 00/23] upgrade to hyper/http 1.0

[Fabian Grünbichler]

this RFC series adapts proxmox and proxmox-backup to hyper/http 1.0. I
also have similar patches for PDM, but those require an update of gloo
and proxmox-yew-comp and the basic approach is the same as with the
patches here, and since I expect some feedback to incorporate anyway I
saved those for the first "proper" version.

hyper 1.0 came with a lot of changes, the most notable ones:

Body is now a trait, not a struct
- there's a new Incoming impl for incoming requests on the server side,
and incoming responses on the client side
- http-body-util has some more impls
- proxmox-http has a new impl covering our two common use cases, see
the patch there for details

hyper now doesn't expose tower's Service or tokio's
AsyncRead/AsyncWrite, but has its own variants for both with
corresponding wrappers/adapters.

the previous Accept trait for translation from a listening socket to
connections is gone, an accept loop should be used instead.

the pooling client is moved from hyper to hyper-util. despite its
"legacy" label we still use it, as we'd need to either implement a ton
of code ourself or switch to reqwest otherwise.

graceful shutdown of connections is handled differently, so are
connection ugprades.

I did some rough testing of the usual things without noticing any
breakage, but I am sure I missed some parts. there's also room for
improvement for sure, in particular surrounding the rest-server and
connection accepting part - suggestions welcome!
