Allow to ignore late data for specified transformations

[yruslan]

Background

Sometime a table can be late as of BAU. And Pramen can pick it up and run the corresponding transformation as soon as the table loads. But before that Pramen currently considers it a failure.

Feature

Allow specifying for a transformation that it can be late (e.g. dependency checks fail), skip it, but not trigger the pipeline failure.

Example

For a transformation dependency

dependencies = [
  {
    tables = [ dependent_table ]
    date.from = "@infoDate"

    passive = true
   }
]

Update. Found a good name for a dependency that is not optional, but does not raise errors if the job is skipped because of it - passive.
