Alignment of Market Price Granularity and Stream Price Granularity

In Streams, we defined Price Granularity as follows

Stream Price Granularity
Price granularity expressed as an exponent. Applies to all Intervals in the Stream.
Not required for all Facets. For example, if the price granularity is -3, and the value is 1500, the price is 1.500 currency units.

And in Market (Product) definition we have:

Price Granularity
PRICE_GRAIN
The allowed price unit, e.g. Price Granularity == 10 means that that any multiple of 10 CURRENCY units is acceptable, but any price not matching, say a price of 9 CURRENCY units, is rejected.

We need to make sure that we do not create confusion between these two definitions.
