Add --csvfile for list_deliverables

list_deliverables produces multicolumn output only in verbose mode,
and even in that mode it doesn't contain data about projects and
latest commits.

To simplify automated processing of that data this commit adds --csvfile
parameter to specify that results should be stored in CSV file.
