Chef runs fail if route propagation is enabled on route tables

[dblessing]

We found that we can't manage route propagation via Chef provisioning at the moment so we just managed the local routes via Chef and then manually enabled route propagation in AWS console. All subsequent Chef client runs fail once propagation is enabled. This is just about a show stopper for us because without propagated routes we can't have traffic routed to/from our VPN.

I guess I should say - either Chef needs to ignore the propagated routes or give us a mechanism to enable route propagation via aws_route_table. Either scenario is acceptable in the near term but we would like to have Chef fully manage this in the long term.

This relates to #151 and #172

Where in the UI do you configure route propogation? I was poking around and couldn't find it.
