just move our config to interfaces.d (#247)

* just move our config to interfaces.d

* debian needs same fix as rpi

* try to recover/upgrade from putting wrong content in interfaces -- restore it

* modify dhcpcd.conf for gui static changes

* cannot comment out jinja2 with #, need to wipe the {%

* deny Lan for dhcpcd, will need work if wifi is used upstream

* attempt to change ip from console without requiring a reboot

* Revert "attempt to change ip from console without requiring a reboot"

This reverts commit 14c7499cdc.

Better not to break an upstream connection

* cleanup the iiab.j2 template --changing only comment lines
