[VVP] Adding preload generation functionality

preload.py discovers and loads implementations of
AbstractPreloadGenerator from any module on sys.path prefixed with
preload_*

Initial support is provided for VNF-API and GR-API.  The templates
will provide a guide for users to provide their values.

Known limitations:
- No support for Contrail.  Preload will be created, but contrail
  parameters will be skipped. This will be addressed in the future.
