Krikri::PluginHelpers::Apache2Module
Apache2Module - pure logic shared by the apache2_module plugin, unit-testable without I/O.
Class methods
Mirrors real community.general.apache2_module's
create_apache_identifier: by convention an a2enmod name shows up
in apache2ctl -M output as "<name>_module", but a few modules
don't follow it. Order matters (text workarounds all run before
the regex ones, and "shib" precedes "shib2", so "shib2" maps to
mod_shib too).
