[RPC][CLI] RPC Specification Parity (Issue #628) (#684)

## Description

This PR aims to build out the RPC specification to have parity (not
backwards compatability) with the V0 RPC specification.

The OpenAPI YAML spec can be viewed
[here](https://editor.swagger.io/?url=https://raw.githubusercontent.com/pokt-network/pocket/rpc-spec-parity/rpc/v1/openapi.yaml).
This compares to the V0 spec which can be viewed
[here](https://editor.swagger.io/?url=https://raw.githubusercontent.com/pokt-network/pocket-core/staging/doc/specs/rpc-spec.yaml)

The CLI endpoints for the `v1/query` endpoints have also been
implemented
