fix: enable annotations

[alexcastilio]

Description

Feature description: when using option enableAnnotation: true advanced metrics should only be generated for pods annotated with retina.sh: observe or pods in a namespace with that annotation.

Bug: When enableAnnotation: true advanced metrics are still being generated for all pods.

Fix:

• add filtering to metrics module based on IPs stored on its cache
• fixed documentation to reflect current behavior (kube-system namespace is not generating metrics by default)
