Merge development branch to main (#141)

* Remove go-toolkit as build requirement for RPM builds if run in CI

* Remove condition around BuildRequires and use go-toolkit for RPM builds

* use go-toolkit for RPM builds

* Install go-toolkit to fulfill build requirements for RPM

* Add golang-race for UBI9 and Alma9

* Fix wrongly named packages

* Fix wrongly named packages

* Fix Release part

* Fix Release part

* Fix documentation of RAPL collector

* Mark all JSON config fields of message processor as omitempty

* Generate HUGO inputs out of Markdown files

* Check creation of CCMessage in NATS receiver

* Use CCMessage FromBytes instead of Influx's decoder

* Rename 'process_message' to 'process_messages' in metricRouter config

This makes the behavior more consistent with the other modules, which
have their MessageProcessor named 'process_messages'. This most likely
was just a typo.

* Add optional interface alias in netstat (#130)

* Check creation of CCMessage in NATS receiver

* add optional interface aliases for netstatMetric

* small fix

+The `nfsiostat` collector reads data from `/proc/self/mountstats` and outputs a handful **node** metrics for each NFS filesystem. If a metric or filesystem is not required, it can be excluded from forwarding it to the sink. **Note:** When excluding metrics, you must provide the base metric name (e.g. pageread) without the nfsio_ prefix. This exclusion applies to both absolute and derived values.
