* shared scripts from test-infra live in //vendor/github.com/knative/test-infra/scripts;
* created `//hack/update-deps.sh` to properly update deps, including test-infra;
* all bash scripts were updated to use the vendored scripts;
Part of knative/test-infra#30.
* Use helpers from prow-tests image for tests
We're consolidating the test infrastructure into a single place, so all repos get the same fixes, updates and new features.
`presubmit-tests.sh` helper is implemented by knative/test-infra#12
`e2e-tests.sh` helper is implemented by knative/test-infra#17
* Explicitly fail test if setup fails
* Create presubmit and end-to-end test infrastructure
Partially addresses #65.
Note that build, unit and integration tests are currently placeholders for the real stuff (see #67, #66 and #30).
* Fixes:
* Correctly wait for knative/serving to be up
* Add proper E2E header, stating that no tests are run
