FR: Support Ubiquiti gear

Is your feature request related to a problem? Please describe.

I have three locations (one Office, two Retail), each with about 3 subnets routed by an Ubiquiti Edgerouter. Each location has a large number of embedded devices on the network that cannot run arbitrary software. I'd like to be able to easily remotely access them without playing with firewall rules, etc.

Describe the solution you'd like

I'd like to install Tailscale on the Edgerouters and announce routes for the attached subnets. It looks like this is theoretically possible with the available binaries, but also I'm busy with real life and don't want to fiddle with stuff.

Possible solutions in order of desirability from least to most:

• Clear, concise HOWTO on how to install tailscale on an Edgerouter in a way that survives reboots and firmware updates.
• An install/configuration script of some kind
• Integration with Ubiquiti's/Vyatta's configuration GUI

Describe alternatives you've considered

I've considered messing around with just downloading the binaries and trying it out, but having a real life has mostly limited time and inclination to do real work on that front.

Additional context

Not sure how much you consider this as in-scope for your work. I like Tailscale because it feels like you have a gentle enough pricing path that it would be attractive for a small business like mine (I have a small office staff that's entirely non-technical) relative to other VPN options. Plus it's technically more sound.
