Rename Docker's PrivilegedServices to ServicesPrivileged
What does this MR do?
Renames Docker's PrivilegedServices config option to ServicePrivileged.
Why was this MR needed?
There's a few other options we're enabling for specifically services, and it made more sense to now have these prefixed.
We haven't yet tagged a version with PrivilegedServices, so doing means we don't have to deprecate the option.
What's the best way to test this MR?
It's just a rename.
