[TASK] Local live testing environment + requesting service for easy PoC

[drewstone]

Overview

We have integration tests using the Blueprint manager, this is great. What we need to push that one step further is a lively testing environment where we can test a running service and demo it for prospective partners (as well as let any Blueprint developer demo their app, connect it to dApps, etc.).

I think this includes

• A local environment mimicking what the integration testing environment requires
• A CLI function that can request services and not deal with payments, etc. (using a dev account like //Alice or something hidden from the user).

I think the overall dev-exp for Blueprints becomes

1. Build your blueprint and test it with unit/integration tests.
2. Use this TASK's primitive to test it locally, lively and demo any connections to dApps, auxiliary services.
3. Deploy to our testnet
4. Deploy to our mainnet
