Keep warming services out of cached adj
Add a pre-configured list that will help to prevent those services
which will keep critical code path of the host processes warm
from falling into cached adj; in case of multi-user, such service
running in the background user won't get this capability, unless it's
singleton.
The list will be empty by default and subjected to be overlaid
by device configurations.
