✏️ Editing: extra_minion_data_in_pillar.py

"""
Add all extra minion data to the pillar.

:codeauthor: Alexandru.Bleotu@morganstanley.ms.com

One can filter on the keys to include in the pillar by using the ``include``
parameter. For subkeys the ':' notation is supported (i.e. 'key:subkey')
The keyword ``<all>`` includes all keys.
