v0.1.6

• breaking change: change var names in network role
  openwrt_network_devices: -> openwrt_network_deviceshost
  -> openwrt_network_devicesgroup
  openwrt_network_interfaces -> openwrt_network_interfaceshost
  -> openwrt_network_interfacesgroup
  openwrt_network_bridge_vlan -> openwrt_network_bridge_vlanhost
  -> openwrt_network_bridge_vlangroup
  now it is possible to define interfaces and devices in the networking
  role also on a host and/or group basis in ansible
  It's the same as this is already been done before in the
  openwrt_network_firewall role

  This was necessary when having bigger environments where interfaces and
  devices are the same on lots of devices. Docs will be changed, too soon.

• optimized deploypath flexiibility
  now just change the var openwrt_*_deployroot to
  the path where you want to deploy your configs to.
  The default is set to "/" so just replace it with what you want
  useful for OpenWrt imagebuilder so you can not only deploy
  configs to real hosts but also into dirs without the handlers

• small bugfixes
