Keep Snapshots

[cpzengel]

Hi, please provide a function to keep snapshots longer on destination!

Managing the number of snapshots like that would require a lot more logic to be run on the destination side.

However, I believe the intended effect can be achieved with zfs hold, by placing a hold on a certain snapshot, and then zfs recv -F won't automatically remove it, but I'll have to do some testing.
