Annotations are ignored for some kinds of resources when syncing

[squaremo]

In sync/sync.go, the manifests (files) are compared with the resources in the cluster, by cluster.Exporting and parsing the latter. But export only includes the kinds of resource we "care" about -- hitherto, namespaces, services and deployments. So an annotation on another kind of resource will not be in the results, and not be taken into account.

This is a problem when using the flux.weave.works/ignore annotation on say, a daemonset resource, because the file will be kubectl applyed regardless.

#747 will expand the set of resources we take notice of (to include daemonsets, among others), but ultimately, we want to know about anything that might appear as a manifest.

I'm puzzled about this: I have used ignore on ConfigMap in the cluster, to stop Flux re-applying the config from git, and believed it was working.

The rewrite of the syncing code in #1442 removed this limitation. Sorry for the confusing leftover issue.
(We should still bring the FAQ up to date -- thanks for filing that issue)
