nss-setup: Refactor and add options for setting up nodes to use DHCP
* Refactor and clean up script and add more helpful docs.
* If a device's MAC doesn't match or isn't specified the following will
be configured:
1.) lan network will use DHCP ("lan_proto=dhcp") to retrieve an IP
2.) device name will be "mx4300-xxxx", where "xxxx" represents the
last 4 characters of the device MAC address found on the bottom of
sticker.
* When in bridge mode, devices can be setup to use static or dhcp for their lan interface.
This is specified with option "lan_proto=dhcp" under each devices's
config, or if no suffix is specified, it is assumed the IP needs to be
optained.
* Add fallback mgmt IP address 10.1.1.1 that can be used in case mesh
fails to come up and hardwire connection is required. Make sure to set
a static IP for your computer in the 10.1.1.x subnet in order to
connect.
