Unable to destroy a cluster

[deeplook]

I was recently testing a fresh github clone of dask-ec2, could perfectly create a cluster with default configuration, but not destroy it again with dark-ec2 destroy (apparently, the instances were not found, see message below), so I had to terminate the instances in the AWS console. Is this a known issue?

Thanks for the report. I think this is because you changed the default region on up but we don't have the same flag on destroy, we should do that and/or save that info in the cluster.yaml.

@danielfrg Sounds reasonable.
