Hi,

Fuel uses pydot-ng, and (at least) taskflow uses pydotplus. I believe
both aren't using pydot because that's dead upstream.

Could we have a bit of consistency here, and have one or the other
component to switch, so we could get rid of one more package that does
the same thing in downstream distros?

Cheers,
