Backporting 4 PRs to release v0.18.4 f Eventing:

cardil and others added 4 commits November 18, 2020 15:47
* Eventing upgrade tests prober fully configurable

* Embedding configuration structs
…e#4442)

Having too long namespace or kservice name can lead to an error like:

```
$ host wathola-receiver-test-continuous-events-propagation-with-prober-zxmkp.apps.example.org
host: 'wathola-receiver-test-continuous-events-propagation-with-prober-zxmkp.apps.example.org' is not a legal IDN name (domain label longer than 63 characters), use +noidnin
```

In this case my namespace is test-continuous-events-propagation-with-prober-zxmkp
and knative service name is wathola-receiver. The namespace is taken
from Go test method name. The limit is 63 characters. In this example
the subdomain is 69 characters.

This does affect OpenShift Serverless as kservices there have a URL
format of `${ksvc.name}-${ksvc.namespace}` to enable usage of TLS
wildcard certificates.

Reducing this test method name length will help fit within this strict
limit of 63 chars.
On OpenShift we've observed a disparity when using pods vs deployments.
Using both of those can lead to having different effective user for a
bare pods and pods managed by deployment.

That leads to differences in reading a config file by wathola
components, as `~` points to different places sender and
receiver+forwarder.

This changes the code to avoid using bare pods for wathola components.
… batch Job (knative#4460)

* Reimplementing fetching of wathola report with K8s job

This change targets the problem of how to get report from cluster.
Clusters may have different networking setup, and it might not be
possible to directly make HTTP request from outside of cluster.

Previous approach used to guess an external address of cluster. That for
sure fails on OpenShift deployed on AWS.

This approach deploys a special Job that, being inside cluster, can
download a report and print it in it's logs. Then test client can fetch
logs of completed job, and parse it, replay the logs, and process report
further.

* Removal of unneeded external node address package

* Fixing lints & boilerplate

* spec.template.spec.restartPolicy=never

* Apply @devguyio suggestions for test/upgrade/README.md
