Title: enable get all metrics in CLUSTER_SERVERS

Enable:
'''/metrics/index.json?cluster=True'''
or
'''/metrics/index.json?cluster=1'''
styles to get all metrics in a cluster not only a single backend.

If '''cluster=''' is provided, it will iterate all servers in this cluster to "GET /metrics/index.json", and merge all json response.
