short_description: return single list completely flattened

description:
|
|
- given one or more lists, this lookup will flatten any list elements found recursively until only 1 list is left.

_terms:

description: lists to flatten

|
required: True
|
|
notes:
|
|
- unlike 'items' which only flattens 1 level, this plugin will continue to flatten until it cannot find lists anymore.
|
|
- aka highlander plugin, there can only be one (list).
