zpm: use "devices" instead of deprecated "file_list" in job desc

This will eventually allow us to copy things more directly from the
zapp.yaml file.
zpm: use "device.name" instead of "device.device" in job desc

The old name has been deprecated.
bundle: copy "count", "replicate", and "attach" into job desc

These values can be copied directly.
bundle: copy "devices" directly when generating job desc

This way we will automatically "support" future keys.
bundle: copy everything from an execution group into job desc

This means that we automatically support new keys in this section.
