Introduce hookless installation for kedify agent

[jkremser]

There are actually 3 modes now when it comes to hooks and creating cr(d)s:

• --set hooks=helm is the default one and this is the status quo so it behaves copletely the same as before => using helm hooks for creating cr(d)s and for cleanup
• --set hooks=jobs is trying to replace the helm hooks w/ ordinary k8s jobs that deletes itself. This is useful for environments that don't render the helm hooks (helm template --no-hooks ... | k apply -f -). Like EKS plugins. Check the (*) caveats section.
• --set hooks=argo. This guy just renders CRDs and CRs w/o any support jobs that is trying to create them. Custom argo annotations are added on those resources in order to make sure the right order is enforced (sync waves for crds (-5) and -4 for cr, default is 0)

For the last two, also init container is added to agent deployment that waits for kedify config CR to exist.

(*): caveats:

1. cleanup in install jobs is best-effort (can't remove the rbac stuff completely, because of rbac that would be missing, resources are deleted 1 by 1 in api server)
2. cleanup for whole helm installation is not doable w/o pre/post-delete hooks so kedifyconfig CR and CRD are left in the cluster because of the finalizer that our agent adds on the CR
3. it's not supported to mix and match these install methods nor upgrade from 1 method to another one. The only supported path for changing from hookless to hookful or vice-versa is uninstall and there reinstall

"1." is okish, just 2 clusterrolebindings are left in the install ns
"2." can cause some headaches and we should document this. workaround:

k patch -nkeda --type=merge kedify kedify -p '{"metadata":{"finalizers":null}}'
k delete -nkeda kedify/kedify crd/kedifyconfigurations.install.kedify.io

How to test this?

helm upgrade -i agent . -nkeda \
   --set agent.kedifyServer=kedify-proxy.api.dev.kedify.io:443 \
   --set agent.orgId=** \
   --set agent.apiKey=kfy_** \
   --set hooks=jobs

or for argo (orgId & apiKey needs to be filled in the argo app):

Pull request overview

This PR adds a new hookless installation mode to the kedify-agent chart by moving CRD/CR bootstrap resources away from Helm hooks and attempting to self-clean those helper resources after installation. It mainly affects the chart’s install/uninstall lifecycle, bootstrap ordering, and hook-based extensibility behavior.

Changes:

• Adds a new top-level hookless value to disable Helm hooks for the chart’s CRD/CR bootstrap flow.
• Converts CRD/KedifyConfiguration install resources to support non-hook execution, including wait logic and self-cleanup commands.
• Disables hook-based cleanup and extra pre/post install manifest helpers when hookless is enabled.
