Create API to estimate order book depth based on defined vAMM shape

[JonRay15]

API Overview

When users are creating or amending their AMM shape we need to be able to give them information on what that will actually mean for them as a user. What shape they're quoting, what it means in terms of range, loss at range, liquidation price etc, so they can make informed decisions.

Since this API will need thorough testing and is complex functionality it has been explicitly included in the spec.
