Cumulus no longer accepts lists in yaml

[mazzystr]

We have yaml that looks like the following... WebIds: - source : SystemsAzA type : resource variable : Web1 - source : SystemsAzB type : resource variable : Web1

Where cumulus passes the value of WebIds to a csv parameter in a cf template

Looks like commit e199287df72cbb35be0752aa2ac99e57da1a7bb3 broke this functionality since item['value']) is being casted to string CFStack.py(109)
