helm - Create keystone public service failed with nil external vip

[Chung Chih, Hung]

helm - Install "keystone-public-svc" failed with nil external vip

When user try to install keystone-public-svc with default value.
Helm will installed failed with following messages

$ helm install microservice/keystone-public-svc
Created tunnel using local port: '41270'
SERVER: "localhost:41270"
CHART PATH: /home/lyan/helm/microservice/keystone-public-svc
Error: error validating "": error validating data: unexpected nil value for field spec.externalIPs[0]

Keystone-public-svc will default enable external port, this will cause svc yaml will
need to get externa_vip value. But it will not been assign any value.
Therefore the svc yaml will output:

externalIPs:
    -

Maybe we should check whether external port had been enable and external vip had been added,
then assign external vip.

The problem is, the packages have no way to know what the external VIP should be for your system. The user must specify them.

Helm currently does not have a way to reject a chart entirely and let the user know they need to specify a required value yet.
