Inter chaincode invokations

[diestrin]

Proposed changes

To be able to invoke a chaincode from inside another chaincode using convector APIs. This was already possible using the stub object, but this ads some shortcuts to do it easily.

Types of changes

What types of changes does your code introduce to Convector?

• [ ] Bugfix (non-breaking change which fixes an issue)
• [x] New feature (non-breaking change which adds functionality)
• [ ] Breaking change (fix or feature that would cause existing functionality to not work as expected)

• [x] Lint and unit tests pass locally with my changes

Further comments

From inside another controller you can make an invokation like this

const adapter = new InChaincodeAdapter();
const secondCtrl = ClientFactory(SecondController, adapter);
const second = await secondCtrl.$config({ tx: this.tx, 'channel-name', 'chaincode-name' }).get(id);
