Synchronize variants of `JsonGenerator#writeNumberField` with `JsonGenerator#writeNumber`

[valery1707]

Currently JsonGenerator#writeNumber supports 7 types (short, int, long, BigInteger, float, double, BigDecimal) but JsonGenerator#writeNumberField support only 5 (int, long, float, double, BigDecimal).
For 2 types (short, BigInteger) we need to call JsonGenerator#writeFieldName and JsonGenerator#writeNumber rather then use one method.

Is it acceptable to create a patch with these two methods?

Yes, that would be acceptable; that's an oversight. Since this is an API change, it will need to go in a minor version and unfortunately this just missed 2.10 (as it is being uploaded). You can make PR against master (which is for 3.0.0) and if things go well I can backport it -- there is no 2.11 created yet.

[valery1707]

Good.
I will create PR soon.

[cowtowncoder]

CLA received, PR ready: will wait until I create 2.11 branch (since it's an API addition), and then merge it.

Thank you for contributing this improvement!

Thank you for this contribution @valery1707 -- it will be in 2.11.0 (I created 2.11 branch).
