1. the expected_reports.csv.res doesn't contains the line with the variable, as it is non expendable in the canonification
2. we can detect line that won't get in the file because variable is not defined - but simply adding the non expended line in the .csv.res file doesn't work either, as it won't be match at log time

1. if we can match an entry in the expected_report.csv.res we use it
2. if not, we expand the results of expected_reports.csv_non_expanded, and look for it inside

risk is performance issue
Idealy, we would not read/write the non_expanded at each non valid report, but use an in memory array

Openned a ticket on CFEngine bugtracker: https://tracker.mender.io/browse/CFE-2830
we cannot use iterator, but we can use plain strings

In 4.1 this is a cfengine problem
This has been solved in 4.3 by changing hos reports work.

Ok, Node properties work. It's "simply" all variables defined in technique editor that cannot be used

All variables defined using generic_variable_definition will also be ignored (in fact using variable that are only defined on agent side doesn ot work in reporting)

Actually, the generic_variable_definition are the only variables (with node properties) that works in reporting in technique editor
