test(satp): create scripts to run the SATP test package

[LordKubaya]

Create a test scripts that can run all the unit and integration tests. This script should be done in the package.json.

Tests that envolve ledgers should be changed so they can be run without creating and destroy ledgers for every test. This will permit the test package to run much faster.

Implement - when tests fail the ledgers do shutdown.

Things to have in mind: In Fabric you cannot create 2 smart contracts with the same name. You need to provide isolation of the tests, even when running in the same ledgers.
