v0.10.2

This release officially removes support for Elixir 1.7 and Elixir 1.8. It turns
out that those versions wouldn't have worked in v0.10.0 due to a dependency that
was added.

• Improvements
  • Add VintageNet.reset_to_defaults/1 so that it's easy to reset a network
    interface's configuration to what it would be if VintageNet.configure had
    never been called. The previous "easy" way of doing this was to erase the
    persisted configuration file and reboot.
  • Clean up interface reachability handling (disconnected vs. lan-connected vs
    internet-connected). There was an issue where the status was out of sync due
    a bug in a technology implementation. This is harder to do now. IMPORTANT:
    if you have a custom technology implementation, calling
    VintageNet.RouteManager.set_connection_status is sufficient. You no
    longer need to update the status property for your interface. This is not a
    common need.
