Subject: [PATCH 1/2] chore(collectd): remove dead VMware/WMI collectors from
 overlay

delta-v does not bundle the VMware or WMI collectors: VmwareCollector,
VmwareCimCollector, and WmiCollector exist nowhere in the repo, no
vmware/wmi collector jar ships in the collectd image (only snmp-collector
is a concrete collector impl), and no vmware-datacollection-config.xml /
wmi-datacollection-config.xml exists anywhere. The collectd overlay still
advertised them, so the config registered implementations that are not on
the classpath and pointed at datacollection configs that do not exist.

Remove the dead config:
- drop the vmware6 and vmware7 packages, the WMI service (already
  status="off"), and the four VMware/WMI <collector> registrations from
  collectd-configuration.xml
- drop the four VMware/WMI <include-collection> entries from
  datacollection-config.xml and delete the now-orphaned datacollection
  groups (vmware6.xml, vmware7.xml, vmware-cim.xml, wmi.xml) in lockstep
  so no dangling group reference survives
- extend the VMware NOTE in shared/poller-services.yaml to record that
  the collectors are gone too, not just the monitors

Every edit removes an optional/repeated element, so the schema-validating
MOXy unmarshaller accepts the config (unlike the RRD-element removals that
hard-fail at parse time). Verified: collectd rebuilt with the amputated
overlay boots Up (healthy), the datacollection config parses with no
dangling group reference, and the collectd producer keeps publishing to
deltav-timeseries with zero failures
(deltav_timeseries_batches_published_total{producer="collectd"} > 0).

Subject: [PATCH 2/2] chore(collectd): strip collectd to SNMP-only, drop
 unbundled collectors

The collectd boot module bundles only the SNMP collector: daemon-boot-collectd/
pom.xml declares SnmpCollector and no other concrete collector. The JMX/Jsr160,
JDBC, Prometheus, WS-Man, and XML collectors that the overlay still registered are
not on the collectd classpath (verified in deltav/collectd:latest: SnmpCollector
is the only concrete collector class present), and delta-v daemons report self and
exporter metrics via /actuator/prometheus -> Kafka -> VictoriaMetrics rather than
through collectd. No node is provisioned or auto-detected with any of these
services, so they never scheduled.

Remove the dead, unbundled collector config from collectd-configuration.xml:
- delete the `opennms` package (OpenNMS-JVM, JMX-Minion, JMX-Kafka, OpenNMS-DB,
  OpenNMS-DB-Stats)
- trim `example1` to its SNMP service, dropping WS-Man, PostgreSQL, Elasticsearch,
  Windows-Exporter, Node-Exporter
- drop the 10 corresponding <collector> registrations (PrometheusCollector,
  XmlCollector, JdbcCollector, WsManCollector, Jsr160Collector for the above)
- add a comment documenting the SNMP-only design so unbundled collectors are not
  re-added

JMX-Cassandra (the cassandra-via-jmx package and its two collectors) is left
untouched here: it is retired separately on chore/collectd-rrd-amputation, and
duplicating that removal would collide. After both land, collectd is SNMP-only.

The result validates against collectd-configuration.xsd from opennms-config-jaxb-
1.0.19.jar (the schema the MOXy unmarshaller enforces at boot), and every remaining
<service> has a matching <collector>.
