[PATCH] netifd: add possibility to switch off route config

[Florian Eckert]

This change adds the new configuration option `disabled` for the route
section, which can be used to temporarily disable the section so that
the route is not set. The advantage is that I do not have to delete the
whole configuration to achieve this.

config route
  option disabled '1
