Merge develop into main (#109)

* Add cpu_used (all-cpu_idle) to CpustatCollector

* Update to line-protocol/v2

* Update runonce.yml with Golang 1.20

* Update fsnotify in LIKWID Collector

* Use not a pointer to line-protocol.Encoder

Fixes a potential bug when `fsnotify.NewWatcher()` fails with an error

* Completly avoid memory allocations in infinibandMetric read()

* Fixed initialization: Initalization and measurements should run in the same thread

* Add safe.directory to Release action

* Add comment

* Lookup core ID from /sys/devices/system/cpu, /proc/cpuinfo is not portable

* Upgrade Ubuntu focal -> jammy

* Pipe golang tar package directly to tar

* Update golang version

* Fix Ubuntu version number

* Add links to ipmi and redfish receivers

* Fix http server addr format

* github.com/influxdata/line-protocol -> github.com/influxdata/line-protocol/v2/lineprotocol

* Corrected spelling

* Add some comments

* github.com/influxdata/line-protocol -> github.com/influxdata/line-protocol/v2/lineprotocol

* Allow other fields not only field "value"

* Add some basic debugging documentation

* Add some basic debugging documentation

* Use a lock for the flush timer

* Add tags in lexical order as required by AddTag()

* Only access meta data, when it gets used as tag

* Use slice to store lexialicly orderd key value pairs

* Increase golang version requirement to 1.20.

* Avoid package cmp to allow builds with golang v1.20

* Fix: Error NVML library not found did crash
cc-metric-collector with "SIGSEGV: segmentation violation"

* Add config option idle_timeout

* Add basic authentication support

* Add basic authentication support

* Avoid unneccessary memory allocations

* Add documentation for send_*_total values

* Use generic package maps to clone maps

* Reuse flush timer

* Add Influx client options

* Reuse ccTopology functionality

* Do not store unused topology information

* Add batch_size config

* Cleanup

* Use stype and stype-id for the NIC in NetstatCollector

* Wait for concurrent flush operations to finish

* Be more verbose in error messages

* Reverted previous changes.
Made the code to complex without much advantages

* Use line protocol encoder

* Go pkg update

* Stop flush timer, when immediatelly flushing

* Fix: Corrected unlock access to batch slice

* Add config option to specify whether to use GZip compression in influx write requests

* Add asynchron send of encoder metrics

* Use DefaultServeMux instead of github.com/gorilla/mux

* Add config option for HTTP keep-alives

* Be more strict, when parsing json

* Add config option for HTTP request timeout and Retry interval

* Allow more then one background send operation

* Fix %sysusers_create_package args (#108)

%sysusers_create_package requires two arguments. See: https://github.com/systemd/systemd/blob/main/src/rpm/macros.systemd.in#L165

* Add nfsiostat to list of collectors
