[stable/prometheus-operator] add secret-field-selector

[Sayrus]

What this PR does / why we need it:

Following prometheus-operator/prometheus-operator#3355, add support for this new option. This should be released in v0.41.0.
This option is used to filter out secrets that are usually watched by the operator but not useful. This includes filtering out Helm V3 secrets which can cause significant CPU and Memory usage or to select only Prometheus Secret if you want to tag them all with a type (or any Field Selector actually).

Which issue this PR fixes

None

Special notes for your reviewer:

This should not introduce any breaking change and should work (not enable the option but not crash the operator) before v0.41.0. I did not version-gate the option for this reason.

Hi @Sayrus. Thanks for your PR.

I'm waiting for a helm member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

/hold

Let’s hold PRs to stable/prometheus-operator chart for a short time until prometheus-community/community#28 (comment) is resolved. If you want to help with that effort, to test etc, that would be great!

@Sayrus as a user and contributor, would you mind helping to review/test this PR? prometheus-community/helm-charts#1

No need to reply here. If you can, please just reply and help there. It would help this process move along faster. Thanks!

🚧 This chart is now deprecated.

Further development has moved to prometheus-community/helm-charts. The chart has been renamed kube-prometheus-stack to more clearly reflect that it installs the kube-prometheus project stack, within which Prometheus Operator is only one component.

If applicable, please re-open this PR there. Thanks!
