+A Proof Of Concept of lookup plugin to query the re2o API.
+
+For a detailed example look at https://github.com/ansible/ansible/blob/3dbf89e8aeb80eb2d1484b1cb63458e4bb12795a/lib/ansible/plugins/lookup/aws_ssm.py
+
+
+For now:
+
+ - Need to clone nounous/re2o-re2oapi.git and checkout to crans branch.
+ - This Re2oAPIClient needs python3-iso8601
+
+TODO: Implement a small client for our needs, this will also remove the sys.path extension ...
