STORY:
As a WMCO developer, I want components that do not make changes to Machine object like metrics configuration to be handled by a separate controller.

DESCRIPTION:
Currently windowsmachine controller is responsible for handling external configuration like Prometheus, even when it does not modify a Windows Machine object. WMCO checks for metrics being enabled on the namespace its deployed only in at startup. WMCO ignores the change if metrics are enabled/disabled while WMCO is running. This should be handled by an independent controller like node controller that checks for the state of Prometheus configuration for any changes.
 
ACCEPTANCE CRITERIA:

• Node controller is extended to handle metrics configuration.
   
• All existing e2e should continue to pass.
