Add code coverage to acceptance tests

[jromero]

Description

#591 adds code coverage for unit/integration tests. In order, to truly know the full coverage of our tests we need to add coverage to acceptance tests.

Proposed solution

The proposed solution would apply to pack=current, create builder pack=current, lifecycle=default when pack itself is built by the acceptance tests. A possible solution could be that instead of it being built to binary, a wrapper/interface could be created that does "magic" when calling operations to pack.

I propose this "hack" because it appears that go run -cover or go build -cover don't exist. The implementation should be a tidy as possible limiting the scope of the "hack" to a very specific section of code.
