### GetConfigKeys(keys []string) ([]byte, error)
Get a json document which contains a set of keys and their values from config.json.
__Example__
``` go
configBytes, err := madmClnt.GetConfigKeys([]string{"version", "notify.amqp.1"})
if err != nil {
log.Fatalf("failed due to: %v", err)

// Pretty-print config received as json.

### SetConfigKeys(params map[string]string) error
Set a set of keys and values for MinIO server or distributed setup and restart the MinIO
server for the new configuration changes to take effect.
__Example__
``` go

if err != nil {
log.Fatalf("failed due to: %v", err)
