Road to field test

[clangenb]

The PoC that is already running contains the following features.

PoC:

Run a demo script that sends some market orders via RPC to the worker, which executes the market logic and sends a merkle-root of the executed orders to the Integritee development. The rust-cli can retrieve a merkle-proof of the the executed order for a particular user, which can then look on the Integritee parachain for the merkle root. Currently, it skips sending the remote attestation for now.

Remaining Tasks for the field test

• Upgrade worker to upstream #45 precondition for some of the other tasks.
• Wrap rust-cli with python #40, needed such that the OLI Systems software can communicate with the worker without having to re-implement the protocol in python.
• Switch to DCAP attestation #43
• Rococo deployment #36, currently we are only running short ephemeral demos against local Integritee test-nodes. We need to deploy an actual long-running Best-Energy worker instance.
• Kusama Production Deployment #44
• Facilitate simple lookup of the merkle-root for a given order. #42
• Create production image that can be deployed #46

Nice to have Optimizations

These optimizations simply increase efficiency and slightly decrease the operational costs (which are anyhow already quite low)

• On-demand execution of direct calls #39
• Don't send processed parentchain extrinsics for all parentchain blocks #38
