Support for Ingress ALB ssl-redirect

[cpboyd]

Fixes #43
Originally #37

From @mike7515:

Support type string in ingress service port and pathType in ingress path to work with Application Load Balancer.

It is required to support the ssl-redirect

This adds the ability to specify a port.name when setting a port: to a string value.
In addition, it prevents service.servicename from overriding a path's local service: name.
