[ClusterResourceSet] Add Sync mode

[sedefsavas]

User Story

As a developer/user/operator I would like to apply a resource using ClusterResourceSet and update its version or change some other fields using the same ClusterResourceSet resource.

Detailed Description

To support this use case, we can consider adding a Sync/Reconcile mode in addition to ApplyOnce mode that reapplies the resources on resource hash change and/or periodically.

@sedefsavas Are we still interested in pushing this forward or should we close it for now?

[sedefsavas]

There were no requests to move this forward, I think we can close it until there are new use cases.

Hi gurus, can we reopen this please? We have a upgrade case that need to re-apply this CRS (with updated secret content). Thanks.

@jessehu I think this issue was essentially superceded by: #4807 Can you please check if the new issue fulfills your use case?

[jessehu]

Exactly! Glad to see it's almost done 👍
