Revamp e2e Tests

[sudermanjr]

• Adding a docker build + kind load command to the e2e test in order to enable external PRs
• Switch to venom for e2e tests
• Add test output of e2e tests. Tied to rok8s-scripts PR
• Added additional test validation

TODO:

• Split the 10_ test case into more than one
• Move the installation of the demo app into the test suite of the tests it applies to and cleanup after
• Release orb so that saving the output works
• Actually fail the build if the tests fail.
• Still report the tests to circle even if the tests fail.
