Fixes for the vCPE vG-MUX install script

This change improves the vG-MUX install script by:
- setting bng-mux network IP and mux-gw IP from environment
  variables instead of hardcoded values
- provides ability to use script to prepare a snapshot image
  with the vpp and honeycomb binaries pre-compiles to improve
  vnf deployment time (was taking about 40 minutes).
