I created this client in order to dump summary stats from the fog-view response.

I got the following results:

If I understand right, this means that mc-mainnet fog has never had a missed block event. That is frankly amazing.

TODO: I would like to be able to hit signal fog this way too.

This change should probably be based only against master. Currently this PR is trying to both merge 4.1.0 to master as well as bring in this new client.

Mostly nit comments

❓ What is the negative affect this prevents? I commented it out and saw nothing negative.

Initially I was thinking to make the final log lines be a json blob on stdout, but I ended up not doing that.
I still think it's usually good for tools to send logging to stderr.

🔧 Looks like there is some stray debug code here

Suggested change
//let mr_signer_verifier =
// mc_fog_view_enclave_measurement::get_mr_signer_verifier(None);
let mut verifier = Verifier::default();
verifier.debug(DEBUG_ENCLAVE); //.mr_signer(mr_signer_verifier);
let mut verifier = Verifier::default();
verifier.debug(DEBUG_ENCLAVE);

yeah we can do this -- honestly it may be better to try to ignore attestation as much as possible here.

💭 This is good enough and seems to be inline with other outputs, but I'm curious who the intended audience is.
The reason is that the resp, while plain text, is not very ergonomic for human scanning as it is one line that is 7000 characters long.
