1. New REST endpoints

**NOTE: these endpoints will actually be removed in Cosmos SDK 0.46.x, but it is still recommended to migrate to them now.

Cosmos v0.40 and later introduced new grpc-REST endpoints and marked the legacy endpoints as deprecated. In v0.46 the legacy endpoints will be removed and the new endpoints will have to be used. The new endpoints are already live since THORChain is on Cosmos SDK v0.42, so these can be migrated to now.

This guide goes over all legacy endpoints and their new counterparts in cosmos v0.40 and later: https://docs.cosmos.network/master/migrations/rest.html
