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

## `diskstat` collector
```json
"diskstat": {
"exclude_metrics": [
"disk_total"
],
"exclude_mounts": [
"slurm-tmpfs"
]
}
```
The `diskstat` collector reads data from `/proc/self/mounts` and outputs a handful **node** metrics. If a metric is not required, it can be excluded from forwarding it to the sink. Additionally, any mount point containing one of the strings specified in `exclude_mounts` will be skipped during metric collection.
Metrics per device (with `device` tag):
* `disk_total` (unit `GBytes`)
* `disk_free` (unit `GBytes`)
Global metrics:
* `part_max_used` (unit `percent`)
