MSB registration

Current registration has a bug by using InetAddress.getLocalHost().getHostAddress().

Thanks to OOM it now possible to register through a simple annotation like the one used in multicloud module

/oom/kubernetes/multicloud/charts/multicloud-k8s/templates/service.yaml

 
annotations:
msb.onap.org/service-info: '[
{
"serviceName": "multicloud-k8s",
"version": "v1",
"url": "/",
"protocol": "REST",
"port": "{{ .Values.service.externalPort }}",
"visualRange": "1"
}
]'

  Should be something similar for nbi
• Remove all java code relative to MSB registration

See application.properties, everything must be removed

1. MSB
   msb.enabled = true
   msb.discovery.host = msb_discovery
   msb.discovery.port = 10081
   msb.discovery.retry = 1
   msb.discovery.retry_interval = 5000
   msb.service.host =
   msb.service.name = nbi
   msb.service.custom_path =
   msb.service.protocol = REST
   msb.service.visual_range = 1
   msb.service.enable_ssl = false
