support s3fs secrets file format
fix copy-truncates-key problem, don't split on the last slash....drop everything in front of the 2nd slash instead
To be compatible with VPC, remove default group for launching instances. Also add --wait option for spot instances. If you request-spot-instances or describe-spot-instances with the --wait option, "aws" will watch for spot request in "open" state. When they are all gone, "aws" will then watch for instances in the "pending" status. When they are all gone, "aws" will exit.
