This PR includes only proto changes and generated code changes.

I have already written the code that does runtime check but I haven't pushed it yet.

The runtime code asserted that every signer is correctly formed.

The only thing I'd need right now for the review is to make sure that cosmos.msg.signer marks the correct field as the GetSigners() implementation.

I mean I've checked it multiple times but an extra pair of eyes helps.

Anyone knows why this test might be failing? First time seeing this.

// The field must either be of string kind, or of message
// kind in case the signer information is contained within
// a message inside the cosmos message.
repeated string signers = 11110000;

repeated string signers = 11110000;
repeated string signer = 11110000;

This is more intuitive naming given how repeated options are declared

Let's change this to v1 before release (or change it now)

Tests added, and added more docs.

We have no real way to test the protoregistry part due to how gogoproto registry works.

The policy in case of missing/malformed signers is a panic.

I was wondering if we should relax it or use a global to set it from panic to warning, reason being unexpected panics due to some unforeseen errors in the registry.

Putting on draft again in order to try to resolve protobuf filenames conflicts in a more elegant way.

What if we just merge the annotations in this PR and deal with the validation in a follow up?

Opening this again for review, removed the validation part as doing the gogoproto registry fix alongside this PR requires too much dependency synchronisation.

What do you think of option (cosmos.msg.v1.signer) = "delegator_address,validator_address"; which would be similar to e.g. the orm indices syntax

Considering the instances in which we have multiple signers, I'd keep it this way, also because the decision to rename the field signers to signer was mainly driven by the most common use case.

But no strong opinion otherwise, let me know.

I'd like to take some time in today's architecture call to present this and other pulsar/app wiring related changes that are coming
