add ability for additional service ports to be added as ports on the deployment/statefulset ports.

[itewk]

Purpose

possible solution for issue #26.

possible issues

• this defaults to always creating any additional service ports as pod ports
  • could keep this as is, i can't think of why you would add an extra service port and not expose the port on the pod
  • could add a flag to say whether to expose the port in the pod
  • could use a completly different dictionary from the service dictionary to speicy the pod ports
• there is a 15 character limit on pod port names that can cause issues
  • not sure how to deal with this one

testing

I have tested this in my environment and it works.
