Ensure all resources are deleted after the tests and reorganize env names

[JorTurFer]

Signed-off-by: Jorge Turrado jorge.turrado@docplanner.com

The main idea of how this works, is that every e2e namespaces are labelled with type=e2e so we can delete them at once always after e2e execution. This is a security mechanism and not a reason to don't clean test resources inside test scope.
Apart from that, some environment variables have been renamed.

Extra point: Azure queue e2e tests now wait till the queue is created to continue because there are some cases where the test follows without the queue and fails

Some Namespaces might be created via yaml:

keda/tests/scalers/influxdb.test.ts

Line 129 in b6bc7b7

kind: Namespace

I haven't check that properly, so there might be another occurencies.

🤦
We should only clean if the context is recovered. Let me check how to solve it
BTW, I forgot to say it but we had to wait till @tomkerkhove adds 2 secrets. App insights e2e test will fail till they are
