Gaia uses SDK general error types

[mpoke]

Problem

Gaia is currently using error types defined here. While this is fine for now, these error types may be deprecated in the future. The goal is for Gaia to define its own general errors. This would help with identifying if an error is from SDK or from Gaia.

See cosmos/ibc-go#3184 and cosmos/ibc-go#3186 as an example.

Closing criteria

Gaia doesn't use error types defined in github.com/cosmos/cosmos-sdk/types/errors.

Why would we do this?

This change would make the cosmos hub the only chain in cosmos that does not use the standard error types.

The errors in cosmos are standardized, precisely so that the chains match one another and development & debugging are easier.

Is there any indication that those error types will be deprecated?

I can understand why ibc-go is doing this, but i cannot understand why Gaia would diverge from standards in this way.

The basic is that I believe that this would create instead of relieving technical debt.

This is the recommendation of the SDK team. cc @tac0turtle
