exporter: dont delete exporter service on daemon deletion

The exporter service and service monitor should not
be deleted if an individual daemon is being removed
from a node. As long as the exporter is enabled with
v18 and newer, the exporter service and service monitor
should exist. Clusters were seeing their metrics stop
collection when the exporter service and service monitor
would disappear, especially when multiple clusters are
configured.
