What is the purpose of the change
Currently Estimate swaps query are not supported via grpc gateway(also known as REST) since grpc gateway does not support querying repeated struct types.
This PR solves the problem by unraveling repeated structs into repeated structs of primitive types then using indexes to group them together in the grpc method layer.
Testing and Verifying
This change is a trivial rework / code cleanup without any test coverage.
