Kube pool manager

Manager for Kubernetes pool, automatic applies configuration (annotations, labels, configSource, role) to kubernetes nodes based on any node spec.

Supports JSON path, value and regexp matching.

Sets following settings on nodes if matched:

• node role
• node labels
• node annotations
• node configSource

Node settings are applied on startup and for new nodes (delayed until they are ready) and (optional) on watch timeout.
