Change IndefiniteRange.value to be an integer

See ga4gh/va-spec#129

@theferrit32 can you shed more light on why this was needed?

[theferrit32]

Having this field (IndefiniteRange.value) be an integer to match the type of the Number.value field makes the graphQL query for those objects a little nicer because you can just ask for a field called value of type integer and it works for both IndefiniteRange and for Number

See item (1) here: broadinstitute/gnomad-browser#1472 (comment)

Here in the graphQL query if I want both IndefiniteRanges and Numbers to be returned in the same response I have to alias one of those value fields to have a different name, since the types don't match:

@ahwagner I will defer to you on this one. If we merge this I think we may need a 1.4 release (unless you think it is acceptable to backport this into 1.3?). Please provide your perspective and proceed with whichever path you see as proper.

@larrybabb will review, remove Andreas as reviewer
