-- 'tag-key' - The key of a tag assigned to the resource. This filter is
-- independent of the 'tag-value' filter. For example, if you use both the filter
-- "tag-key=Purpose" and the filter "tag-value=X", you get any resources
-- assigned both the tag key Purpose (regardless of what the tag's value is),
-- and the tag value X (regardless of what the tag's key is). If you want to
-- list only resources where Purpose is X, see the 'tag':/key/=/value/ filter.
