OpenWrt/LEDE interfaces metrics to Influxdb

Simple scripts to push router's interfaces metrics to the influxdb's database.
First iface-metrics.sh - main script to grab and push metrics.
Second: iface-metrics-wrapper.sh - wrapper to help execute first one. Especially to run the main script in the backgroud and grab metrics from all of the interfaces.
