Attach labels or annotations to the namespace of a release

[ilya-lesikov]

Currently, the namespace user deploying to is not managed as part of a release and created before creating the release. This means there is no way to attach labels/annotations to this namespace during werf converge unless the namespace is created and configured before werf converge.

We need a way to specify labels/annotations for all werf commands that create namespaces, i.e. werf converge and werf bundle apply.

Can be achieved with --namespace-labels and --namespace-annotations cli options and deploy.namespaceLabels{} and deploy.namespaceAnnotations{} settings in werf.yaml.

Currently if you need to add some labels/annotations to the release namespace the easiest way is to kubectl label/annotate myns ... after werf converge.

Alternatively, you can do kubectl create ns myns yourself, then kubectl label/annotate, then werf converge.

We are thinking about adding something like --namespace-labels/annotations, but there are some issues with namespace locking.
