grafana-agent: only enable the node_exporter collectors that we explicitly enable

Browse source 
The node_exporter integration in grafana-agent enables a lot of
collectors by default.
We don't want those defaults. We want to opt-into each manually.

See https://grafana.com/docs/agent/latest/static/configuration/integrations/node-exporter-config/
for the difference between enable_collectors and set_collectors, and a
list (table) of collectors that would otherwise be enabled by default.
