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
