✨ import global ci workflow (#418)

This will import the global CI workflow, which runs the end to end tests
defined in https://github.com/konveyor/go-konveyor-tests (for now, it
will be expanded to more suites as they become quick and stable enough).
This helps to ensure that individual components aren't breaking the
project as a whole, which should help to smooth out the release process.
