[puppet4] Fix fuel::mcollective task
[puppet4] Fix fuel::mcollective task

Mcollective module used in Fuel provides string values
to ':order' field of mcollective::*::setting resources,
while fuel::mcollective task also supplies integer values.

In puppet3 that was fine because all values provided
to resources were stringified, but in puppet4 they aren't.
This causes failures of comparison inside datacat_collector
resource used in mcollective module.
