This patch adds the logical switch identifier in the model class for describing mappings between neutron and nsx switch ports. This will allow for a better handling of the chained logical switch use case. This patch also moves the routines for retrieving nsx identifiers in a separate module in preparation for the introduction of async operations and renames relevant model classes, attributes, and functions from 'nvp' to 'nsx'.
