Hello Maintainers

It seems that some Prometheus metrics changed in ETCD for V3.5:

https://etcd.io/docs/v3.4/upgrades/upgrade_3_5/

Which means that there's metrics "not supported" for:

https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/app/etcd_http/template_app_etcd_http.yaml?at=release%2F6.2

For this version, the following changes need to be made:

• etcd_debugging_mvcc_delete_total -> etcd_mvcc_delete_total
• etcd_debugging_mvcc_db_total_size_in_bytes -> etcd_mvcc_db_total_size_in_bytes
• etcd_debugging_mvcc_put_total -> etcd_mvcc_put_total

Regards
