Requirements

Currently, the fractional operator in the in-process provider is percentage-based; meaning you must specify the relative distribution of the variants in terms of a percentage. Consistent with flagd, we should change this instead to be a relative weight, meaning that the integers do not need to sum to 100. For example, this fractional:

"fractional": [ [ "red", 25 ], [ "blue", 25 ], [ "green", 25 ], [ "grey", 25 ] ]

Would remain valid, but could also be expressed as:

"fractional": [ [ "red", 1 ], [ "blue", 1 ], [ "green", 1 ], [ "grey", 1 ] ]
