geoprobe: simple geolocation probing refactoring

[Soptq]

More info in #498 .

@shelvenzhou I think this one should be the target contract ecdh pubkey.

[h4x3rotab]

This is the last remaining problem

[h4x3rotab]

@kvinwang I guess there are easier ways to write Errors?

I guess there are easier ways to write Errors?

There is a crate derive_more to #[derive(Display)] for no_std and a thiserror for std.

[h4x3rotab]

We already have anyhow as pruntime is like a binary than a library. What do you suggest?

[kvinwang]

We have added some memory statistics in the get_info on the master.
Could you please compare the memory usage between with and without geolocation enabled?

You can get the mem stat with this command:

$ curl http://localhost:8000/get_info | jq -r '.payload | fromjson | .memory_usage'
{
  "rust_peak_used": 174590146,
  "rust_used": 51173836,
  "total_peak_used": 278560768
}

[h4x3rotab]

Almost LGTM. Only left the ECDH key problem. I will chat with @shelvenzhou offline about it.

Btw, if you want to update the proto file reference, you just need to cd to the proto directory, use git checkout to locate it to the correct branch / commit, then return back to the main repo and run git add proto/.

  "rust_peak_used": 174590146,
  "rust_used": 51173836,
  "total_peak_used": 278560768
}

With geolocation enabled:

MemoryUsage {
    rust_used: 1180828,
    rust_peak_used: 74689956,
    total_peak_used: 115478528,
}

Without geolocation enabled::

MemoryUsage {
    rust_used: 1034493,
    rust_peak_used: 3656772,
    total_peak_used: 42037248,
}

Both memory statistics are sampled at the end of the e2e test.

LGTM. We are ready to merge. The feature not enabled by default, right?

Yes, disabled by default.
