improvements for launch index, one fix for cloud-archive

1. Docs for launch-index + examples
2. Tests for launch-index + data files
3. Fixing a bug with cloud-archive yaml types allowed (likes a tuple not a list
   for some reason) (LP: #1044594)
4. Setting the 'part' content-type if what we actually use is different.

LP: #1044594
