Fee upgrade

[ss-es]

Closes #3253

This PR:

Contains miscellaneous fixes and configuration options for upgrades, including:

• settings for when HotShot should attempt or give up on an upgrade.
• providing uniform serialization/deserialization via the VersionedMessage trait, which uses a decided upgrade certificate to correctly handle message versioning.
• decoupling serialization/deserialization from the ConnectedNetwork trait; network implementations are no longer responsible for versioning their messages, and only handle raw bytes. Versioning and de/serialization are left to the network event and message tasks.

This PR does not:

Places to review

The libp2p-networking crate, the hotshot/src/traits/networking/libp2p_network.rs file and the request.rs/response.rs files are probably the most significant.

In the libp2p_network.rs file, there is also a lingering type mismatch I couldn't track down, but that I resolved with:

                    let res: Message<TYPES> = bincode::deserialize(&msg.0[8..])
                        .map_err(|e| NetworkError::FailedToDeserialize { source: e.into() })?;

This should be the only place bytes are manually dropped from the message; if you have any idea where the leading 8 bytes might be coming from or a better way to fix this, please let me know!

Instructions:

The sequencer must now provide:

start_proposing_view
stop_proposing_view
start_voting_view
stop_voting_view

Suggested values are:

start_proposing_view: 5,
stop_proposing_view: 6,
start_voting_view: 10,
stop_voting_view: 11,

Testing

The example upgrade should now run to completion without error, with:

RUST_LOG=error,hotshot_task_impls=info just cargo run --example all-push-cdn --features example-upgrade -- --config_file ./crates/orchestrator/run-config.toml

RUST_LOG=error,hotshot_task_impls=info just cargo run --example all-libp2p --features example-upgrade -- --config_file ./crates/orchestrator/run-config.toml

RUST_LOG=error,hotshot_task_impls=info just cargo run --example all-combined --features example-upgrade -- --config_file ./crates/orchestrator/run-config.toml

In general the change looks very good to me. I have only one minor comment at the moment regarding a lock. I also would like to have a closer look at the libp2p changes to fully grasp them. Those 8 bytes bother me a bit so I'll try to get to the bottom of it.

[lukaszrzasik]

I think it would be better to drop the write lock before calling an async broadcast. Just to be sure.

I think it's good to go.
