Rudder

In #5682, we introduced a new format for the ncf configuration file, by using a mustache template

We need to modify the way it is handled by the script rudder-upgrade which sed in it, regardless of the context
We need to obtain, at the end, a config file that owuld look like

{{#classes.any}}
# Which logger(s) should be used in ncf? (comma separated list)
loggers=_logger_default
{{/classes.any}}
# Which port should be for CFEngine connections/data transfers
{{#classes.community_edition}}
cfengine_port=5309
{{/classes.community_edition}}
{{#classes.enterprise_edition}}
cfengine_port=5308
{{/classes.enterprise_edition}}
