you to have App::Netdisco Worker plugins in other namespaces.
Plugin modules can either ship with the App::Netdisco distribution itself, or
be installed separately. Perl uses the standard C<@INC> path searching
mechanism to load the plugin modules. See the C<include_paths> and
C<site_local_files> settings in order to modify C<@INC> for loading local
plugins. As an example, if your plugin is called
"App::NetdiscoX::Core::Plugin::MyPluginName" then it could live at:
"App::NetdiscoX::Worker::Plugin::MyPluginName" then it could live at:
~netdisco/nd-site-local/lib/App/NetdiscoX/Core/Plugin/MyPluginName.pm
