Add explicit class params for setting storeage ports
Add explicit class params for setting storeage ports

Previously, all of the ports used by the storage
class were hardcoded.

This commits adds the following class parameters to
the swift::storage class to allow for configuration
of the ports used by a storage server:
  - object_port
  - container_port
  - account_port
