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

## `numastat` collector
```json
"numastats": {
"send_abs_values" : true,
"send_derived_values" : true
}
```
The `numastat` collector reads data from `/sys/devices/system/node/node*/numastat` and outputs a handful **memoryDomain** metrics. See: <https://www.kernel.org/doc/html/latest/admin-guide/numastat.html>
Metrics:
* `numastats_numa_hit`: A process wanted to allocate memory from this node, and succeeded.
* `numastats_numa_miss`: A process wanted to allocate memory from another node, but ended up with memory from this node.
* `numastats_numa_foreign`: A process wanted to allocate on this node, but ended up with memory from another node.
* `numastats_local_node`: A process ran on this node's CPU, and got memory from this node.
* `numastats_other_node`: A process ran on a different node's CPU, and got memory from this node.
* `numastats_interleave_hit`: Interleaving wanted to allocate from this node and succeeded.
* `numastats_numa_hit_rate` (if `send_derived_values == true`): Derived rate value per second.
* `numastats_numa_miss_rate` (if `send_derived_values == true`): Derived rate value per second.
* `numastats_numa_foreign_rate` (if `send_derived_values == true`): Derived rate value per second.
* `numastats_local_node_rate` (if `send_derived_values == true`): Derived rate value per second.
* `numastats_other_node_rate` (if `send_derived_values == true`): Derived rate value per second.
* `numastats_interleave_hit_rate` (if `send_derived_values == true`): Derived rate value per second.
