Add the certivibe-test repository as a submodule, add a test runner project
Created by: jlegeny
This PR adds the certivibe-test repository as a submodule of certivibe
Several CMake projects are added to facilitate running tests from the 'master' CMake
test-run-cmake test-run-build test-run
Note that the project is called test-run because the name 'test' is forbidden for some reason
