Before this patch, both the RdtEnabled and BlockIOEnabled are provided
by services/tasks pkg. Since the services/tasks can be pkg plugin which
can be initialized multiple times or concurrently. It will fire data-race
issue as there is no mutex to protect `enable`.
This patch is aimed to provide wrapper pkgs to use intel/{blockio,rdt}
safely.
