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

+#cloud-config-archive
+
+# This is an example of a cloud archive
+# format which includes a set of launch indexes
+# that will be filtered on (thus only showing
+# up in instances with that launch index), this
+# is done by adding the 'launch-index' key which
+# maps to the integer 'launch-index' that the 
+# corresponding content should be used with.
+#
+# It is possible to leave this value out which
+# will mean that the content will be applicable
+# for all instances
