[Feature Request]Add support for secret annotation so only annotated secrets trigger rolling update

[johnphilipscs]

I am using your controller to trigger our app to perform a rolling update when cert-manager renews a certificate. It is my preference to restrict the trigger to only occur on the particular certificate secret and not on changes to other secrets.

Still interested in this feature if anyone is working on this project.

I guess ideally this annotations would be on the deployment side instead of the secret side. Otherwise, you might disable it for multiple deployments at once. We could create some kind of whitelist or blacklist annotation on the deployment. What do you think?

@toelke do we want to support this?

Options:

1. Support wave.pusher.com/update-on-config-change: "only-annotated" on Deployments. Add wave.pusher.com/update-deployment-on-config-change: "true" to Secrets/CMs.
2. Add a flag to wave to change the default behavior. Add wave.pusher.com/update-deployment-on-config-change: "true" to Secrets/CMs.
3. Add wave.pusher.com/ignore: "true" to Secrets/CMs to selectively ignore Secrets/CMs. (Kind of different from the request)
4. Decide not to implement this.
