Research an integration framework and create PoC

[julienrbrt]

Research at existing integration frameworks in and outside the ecosystem.
Apply the findings to the SDK (tests/integration) in the PoC to demonstrate to the team.

The recommended features of the integration framework PoC:

• Allow to test modules with their minimal dependencies
• It should allow integration tests to be back under x/{module} without increasing the dependency graph

The shortcomings of the current way, is tests are far from what is being tested and importing not only their module dependencies.
