distance query doesn't support * operand type

[dingle]

Example:

>>>d1 = D(mi=10)
>>>d2 = D(mi=20) 
>>>qs = SouthTexasCity.objects.filter(point__distance_gte=(pnt, 0.5*d1 + 0.5*d2))

It raised:

TypeError: unsupported operand type(s) for *: 'float' and 'Distance'

But obviously it works fine with addition and subtraction. I think it will be nice that

multiplication be implemented as well.

Mutiplication is supported, but only in right form: d1*0.5 would work. But yes, rmul seem to be forgotten at Distance class.

(In [11898]) Fixed #12390 -- Distance and Area objects now support multiplication when they are the right-hand side.
