Export / Import FULL lineage of a given file or a data source

[wajda]

Imaginary example:

1. I have a file A on HDFS, and its lineage in Spline
2. I want to copy A to a different infrastructure (network, cluster, cloud, you name it), monitored by another independent Spline instance. And I don't want to loose the lineage of A
3. Using Spline UI or CLI I dump A's full lineage to a file and carry it with A to a new infrastructure
4. There the lineage dump can be imported manually (again by using UI or CLI), or even automatically on the first Spline tracked read from A.
