Can't set replicaCount to 0 #195

You are not able to set a replicaCount to 0. Doing so results in a 1 replica instead of 0 replicas. The use case is this is that I'd like to scale down the minecraft server while making other changes to the chart. However, when I apply the chart it keeps scaling it back to 1.

This is pretty easy to repro by running:

helm template   --set 'replicaCount=0' --set 'minecraftServer.eula=true' ./charts/minecraft | grep replicas

which returns

  replicas: 1

However using other values works:

helm template   --set 'replicaCount=3' --set 'minecraftServer.eula=true' ./charts/minecraft | grep replicas

returns

  replicas: 3

I believe this is caused by: helm/helm#3164

That issue is attached to several work-around PRs, which may be helpful to resolve this.
