enb: add measurement modifier to scenario files

this commit adds basic support for configuring measurements in the
eNB config. It currently support A1, A2, and A3 events.
By default UE measurements are turned off and need to be enabled by
configuring an event with:

+mod-enb-meas-event@{name},{report_type},{value},{hysterisis},{time to trigger}

For example one can update the a2 and a3 event with:

+mod-enb-meas-event@a2,rsrq,-40,2,480+mod-enb-meas-event@a3,rsrp,6,1,512
