Add service and interface whitelist/blacklists
This allows service whitelists and blacklists, and
interface whitelists to be passed into the application.
The whitelists can be prefixes, like xyz.openbmc_project.
The blacklist is the full service name.
A future commit can add support for interface blacklists.
