[Feature Request] Managing dependencies for the Rust SDK about sdk-core

[Sushisource]

@djc I'm happy to accept pulls for removing mockall (can definitely be done, not necessarily easy) and otel (probably pretty easy to make optional).

The separate hasher crate is used for because the one in stdlib is deprecated.

The convenience macros I find pretty useful. The savings would have to be quite significant for me to want to remove them, and I have no idea what those savings would be without seeing. I can't imagine they're causing a huge amount of bloat.

And yes the tonic bump is just waiting on otel.

Can you briefly explain what the goal/use case of the MockManualWorkerClient is?

For testing of course. But, in production it's used to enable replay workers:

sdk-core/core/src/replay/mod.rs

Line 74 in a764405

let mut client = if let Some(c) = self.client_override {

This could be un-done and replaced with something else, but it's not trivial.
