On first run, replicate the existing snapshots on the source

[phuybre]

Currently simplesnap ,when run on a new filesystem, will create a snapshot on the source and send it to the target. This will ignore all the pre-simplesnap snapshots and start tracking source snapshots from when simplesnap was first run.

It would be nice to replicate all pre-existing snapshots.

It doesn't help of course that zfs has no command to send everything from start to snapshot without also getting all descendant filesystems.

Hi,

Probably it shouldn't do that by default, but I would agree that it
could be a useful option.

Thanks for the suggestion.
