Run e2e tests in GHA

Setup a matrix that runs all current integration jobs in
GitHub actions.

Re-use the setup-kind.sh script from the plumbing repo that
is used today to run these jobs in prow, so that virtually
no change to the jobs is needed.

Once this is in and proven stable, the kind part can be
turned into a reusable action step, hosted in the plumbing repo,
that all Tekton projects may use.
