Initial VES for DANOS vRouter

1. Create vpp_measurement_reporter that use DANOS configd query
   to retrieve statistics and libevel to transmit
2. Copy VES evel library to build a debian package under
   vpp_measurement_report
3. Add debian files to create a vpp_measurement_reporter + libevel
   debian package
4. Add debian install and systemctl start files
5. Add instruction to build VES reporter debian package (that will
   include libevel.so)
6. Add instructions to build DANOS ISO with VES reporter debian
   package and creating glance image
