Fix bug 1931: adds missing parameter

ns_config now includes initial replicaCount to set a start point for the deployment.
Also, the logic for pod number counting is change with `kubectl` command to get
real time pod count. `Get Vnf Kdu Replica Count` method gets the replicaCount information
from osm configs.
