Certain services have custom server lits handling which I had forgotten
about, so although it would have been nice to have this refactor, we'll
have to live with relying on the plugin properties object directly for a
while.
This also reverts obsproject/obs-studio#6530 and
obsproject/obs-studio#6683 because that change depended on this
problematic refactor code.
This reverts commits:
