[v8r5] New TS plugins
In order to streamline the prestaging (and the removal when processed) of files and their ancestors (typically RDST and RAW files for and after stripping), 2 new plugins are introduced:
- replicateWithAncestors
- removeReplicasWithAncestors They make use of replicateToLocalSE and removeReplicasWhenProcessed respectively, and just add the ancestors to the transformation and to the tasks.
