The example includes a restonf, netconf, CLI and two backend plugins.
Each plugin is initiated with an API struct followed by a plugin init function.
The content of the API struct is different depending on what kind of plugin it is. Some fields are
meaningful only for some plugins.
The plugin init function may also include registering RPC functions.
