Improve the generation init-tasks by database migration on Kubernetes/OpenShift

[Sgitario]

This pull request includes the following changes:

• Change default image for init container waiters to groundnuty/k8s-wait-for:no-root-v1.7 which is compatible with OpenShift because it's rootless
• Allow users to disable the generation of an init task by specifying it by name.

Fix #33097

[Sgitario]

It seems that - Allow users to modify the init container image to use. needs to be done on Dekorate side, so I've removed the commit from here.

I know we used it before your patch but I didn't notice it. Are we sure using this image is safe? I'm a bit worried about it.

Never heard about it.... We need to have a deeper look.

The fact that it uses Alpine is not a great start...

[Sgitario]

Since this image seems to be commonly used by the community for this purpose and also it was already used before these changes, I think the way to proceed is to open a new issue to investigate how secure it is and the alternatives.

@cescoffier @gsmet @iocanel do you think we can merge these changes that improve this existing feature or do you prefer put it hold off?

[iocanel]

I wouldn't hold off this pull request because of the image. We need to track it in a separate issue.

[maxandersen]

What image was used before ? Yeah. We should not be using/proposing alpine unless absolutely no other option.

What is the requirements for the image and why not use the base images we otherwise use here ? (That would mean 0 mb extra to fetch :)

[iocanel]

LGTM

Added an optional suggestion. Which can be part of this or a follow up request.

Regarding the image, I think that it needs to be tracked / addressed by a different issue / pr.

The test failure is unrelated. Merging.
