Feature Request: ZeroTier configuration options

[bimbar]

I have redundant opnsense firewalls in a zerotier network and I do not want them to receive routes configured in zerotier webinterface.

So it would be really nice to be able to configure some features in the opnsense webinterface like "AllowManaged", which could stop zerotier pushing routes to the opnsense firewalls.
Right now the only way to do this is to login via ssh and use zerotier-cli.
