SRI - Implement an endpoint to fetch implement an endpoint to fetch StateTreeLeafValueContent object with accompanying info from the BPI, based on the provided CAH

[ognjenkurtic]

Overview

Once the CAH storage is implemented on-chain #805 , we want the BPI to expose an endpoint so that an interested party can fetch all the data related to the execution of the workstep that led to the creation of that CAH.

We need to do this by implementing an endpoint in the BPI that will accept a CAH and return the related StateTreeLeafValueContent object, together with the related state and history tree entries.
