I think it's time to drop the ifnet settings plugin. Please review.

Note that configure.ac used to partly detect --with-hostname-persist= based on the chosen distro plugin. Please note that this might change some behavior there. Does it affect anybody in a bad way?
Probably distributions should anyway explicitly select --with-hostname-perist.

although they are deprecated and unused, document them.
The option is deprecated together with the ifcfg-suse settings plugin.
Selecting the plugin has no effect at runtime, beside logging a warning.

Drop the configure option.

Note, that if $distro_plugins was set to "ifcfg-suse", it was also used to
autodetect --with-hostname-persist=suse. Now, autodetect the hostname
persist mode based on presence of /etc/SuSE-release file.
Even Gentoo disables this plugin since before 0.9.8 release
of NetworkManager. Time to say goodbye.

If somebody happens to show up to maintain it, we may resurrect it
later.

If "$distro_plugins=ifnet" was set, configure.ac would use that
to autodetect --with-hostname-persist=gentoo. Drop that autodetect
part too.

The ifnet plugin is not maintained since long time, so LGTM.

If someone still configures with --enable-ifnet, maybe we should print
an error instead of succeeding without notice (at least for some time)?

The same could be done for --enable-ifcfg-suse, but ./configure already warns about unknown --enable switches. I think that is good enough, I really doubt somebody is using these plugins successfully.

I dislike the change in behavior how we detect the persist-hostname option, but I again think that nobody cares.

Gentoo maintainer here: I'm fine with dropping it. We have been disabling it unconditionally since 2014.

When NM is restarted and a new object-manager is created, ensure that
signal handlers are disconnected from the old one.
