Add E2E testing for ES Rollover feature

[iblancasa]

Which problem is this PR solving?

Add E2E testing to the Rollover ES feature implemented in #267

Short description of the changes

• Add E2E Test for the Rollover ES feature
• Add index job assert to work with ES indices
• Add more capabilities to the reporter assert job to being able to report more spans in different ways
• Add a cmd to wait until a job scheduled by a cronjob is executed successfully tests/cmd-utils/wait-cronjob/. I tried to detect this using the events from the Kubernetes API and Kuttl but there is a problem and the matching between objects is not correct
• Small changes in kuttl-test.yaml to avoid errors trying to recreate the jaeger-operator-system Kubernetes namespace

This looks good but some lint/code style issues needs to be fixed before, so the CI can pass.

@rubenvp8510 I'm not able to reproduce the issue. It seems to be a one-timer issue... Could we re-run the GitHub workflow?

[iblancasa]

I was able to reproduce the issue and pushed a change that can solve the issue and make the tests more deterministic
