Propagate global properties to managed clusters

[mnkg561]

Is this a BUG REPORT or FEATURE REQUEST?:
FEATURE REQUEST

What happened:
There might be a requirement where administrators wants to propagate some properties to the managed clusters. This can be a Global param as Instance ID or cluster specific parameter such as AWS Account# or cluster name.

We should think about a way to propagate this data to all the way to managed clusters. It can be as simple as a config map in the target cluster and update the config map accordingly.

What you expected to happen:
There should be a way to know some default values at the cluster side which can be managed by Administrator from central place.

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:

Environment:

• manager version
• Kubernetes version :

$ kubectl version -o yaml

Other debugging information (if applicable):

- controller logs:

$ kubectl logs
