HostPhysicalComponentTooHot throws "many-to-many matching not allowed: matching labels must be unique on one side"

[baurmatt]

The HostPhysicalComponentTooHot alert throws the following warning:

execution: found duplicate series for the match group {instance="host.docker.internal:9100"} on the right hand-side of the operation: [{__name__="node_uname_info", domainname="(none)", instance="host.docker.internal:9100", job="nodeexporter", machine="x86_64", nodename="nas01", release="5.15.0-107-generic", sysname="Linux", version="#117-Ubuntu SMP Fri Apr 26 12:26:49 UTC 2024"}, {__name__="node_uname_info", domainname="(none)", instance="host.docker.internal:9100", job="nodeexporter", machine="x86_64", nodename="nas01", release="5.15.0-105-generic", sysname="Linux", version="#115-Ubuntu SMP Mon Apr 15 09:52:04 UTC 2024"}];many-to-many matching not allowed: matching labels must be unique on one side

This is because some labels of the node_uname_info metric changed (due to system upgrades) and thus metric is duplicated (for some time).

And these I have come across so far with the same issue:

HostOutOfMemory
HostUnusualDiskReadRate
HostHighCpuLoad
HostCpuHighIowait

This is a duplicate of #397. I'm updating the original issue that it affects more alerts.
