Add Primitive attribute to indicate importance of ordering

- As a user of Featuretools, I want to know which primitives are affected by the ordering of the data.
- We can add `ordering_is_important` to the base Primitive class.
- Default to False
- Make it True for:
- AbsoluteDiff, CumMax, GreaterThanPrevious, IsMaxSoFar, RollingMean, Lag, NumericBin.
