-/// The @c BaseConfigBackendMgr is a base class for all PQMs implemented

-/// backend factory functions and to create instances of the backends using
-/// those factory functions as a result of server configuration. The mechanism
-/// of factory functions registration is useful in cases when the config
-/// backend is implemented within the hook library. Such hook library
-/// registers factory function in its @c load function and the server
-/// simply calls this function to create the instance of this backend when
-/// instructed to do so via configuration. Similar mechanism exists in
-/// DHCP @c HostMgr.
-///
-/// Unlike @c HostMgr, the PQMs do not directly expose API to fetch and
