Create an end to end test (in go) that creates an EventListener

[bobcatfish]

Expected Behavior

We should have a suite of end to end tests that we can use to test triggers functionality. We can start with a simple one that:

1. Creates an EventListener
2. Confirms it is created
3. Deletes the EventListener
4. Confirms it is deleted

(If #36 happens first, this test can actually look for a running container, otherwise this will be a very light test!)

Actual Behavior

We've got a dummy test but not actually invoking any of our libs yet :D

Additional Info

One question at this point is do we want to use the knative test lib? I think it's probably simpler to use it, e.g.:

https://github.com/tektoncd/pipeline/blob/b91640d7db3d2de6fcb8c30c618a417047a03c12/test/embed_test.go#L69-L70

However it's not that complicated to implement our own (this is an example of what's required to hit most of the common stuff we'd need to do) https://github.com/bobcatfish/testing-crds/blob/master/client-go/test/cat_test.go#L136

Up to the implementer of this issue 😉 and also something we can easily change later!

@bobcatfish @vdemeester
For these Tekton Triggers go tests, should we follow the Pipeline repo's test format, and use the knative.dev/pkg/test library? For example, we'd probably create an init_test.go file similar to the one in Pipelines.

I think so, yes

Ok, thanks

Closing this issue because we merged PR #53 👍
