> Enhanced config {{yarn.nodemanager.resource.memory-mb}} has a maximum value of {{268435456
MB}} which comes from the static stack-definition of the config. However the real maximum
of this config is given by the /recommendations call - which calculates it based on the machine's
actual memory.

> Wherever configs are shown (installer, service-config, host-page, add-service, etc.),
we need to override the static stack-default property_attributes with the /recommendations
given property_attributes.
