This plugin api provides functions for resourced.
Provided functions:
* plugin_resourced_low_memory_killer_get_backend: get backend library
* plugin_resourced_low_memory_killer_put_backend: put backend library
* plugin_resourced_low_memory_killer_get_kill_candidates: choose kill
candidates from procs/apps list.
