If we don't want to show any host names in graphs/legend, it makes sense to not resolve them.
I occasionally notice the issue with name resolution of IPv6 addresses on certain networks, which makes `chronyc tracking` take 20+ seconds. Adding -n makes it almost instantaneous.
this helps use the same configs on multiple nodes where not all the
patterns expand to existing files on all of them or when files are not
yet existing
Some SNMP implementations actively report the interface speed as 0 (e.g., when disconnected). This led the plugin to report both min and max to be 0, which later confuses RRDTool, with errors such as
[ERROR] Unable to create '/var/lib/munin/example.net/192.2.0.1-snmp_if_combined_vlan-37-send-d.rrd': failed to parse data source 600:0:0: min must be less than max in DS definition
when trying to creates the RRDs. Ultimately, this would prevent the graph creation from suceeding with errors such as
[ERROR] In RRD: Error updating /var/lib/munin/example.net/192.2.0.1-snmp_if_combined_vlan-37-send-d.rrd: opening '/var/lib/munin/example.net/192.2.0.1-snmp_if_combined_vlan-37-send-d.rrd': No such file or directory

The data was incorrectly loaned from a `temp` subgraph, which should
have been `temperature`.
This led to errors during munin-graph, as follow
[ERROR] Failed to find windChill source at temp.windChill, skipping field
[ERROR] Failed to find heatIndex source at temp.heatIndex, skipping field

This fix allows to skip validity checks on any intermediate certificate
which subject hash appears in the list.
Let's Encrypt certificates are cross-signed by both DST Root CA X3 and
ISRG Root X1. DST Root CA X3 has expired on 2021-09-30 [0], which causes
the plugin to incorrectly report some full-chain LE certificates as
expired.
