Support property naming strategy for Guava Ranges

Follow up PR for #56. Unsure if the public constructors are better off with a different overload structure to preserve backwards compatibility.

Ok. So, what I was thinking was to apply transformations right within createContextual() and pass transformed names; or, transform within constructor. While overhead of name transformations may not be humongous it is something that can be pre-computed.

But other than that I think this makes sense.

note: JDK 8, can not use for Jackson 2.x

I merged unit test part (well, second of tests) in 2.10, to help verify, merge the fix.

Thanks @cowtowncoder. I have fixed it to transform the names in createContextual and have removed the JDK 8 usages. LMK if there is a better way to do this.

@philleonard Looks good, I think, any tweaks I can think I can do post-merge I think. The only other thing is that I'd like to get this in 2.10, will see what'd be the best way.

Just one other thing before I can merge this: if I have not yet asked for CLA (https://github.com/FasterXML/jackson/blob/master/contributor-agreement.pdf), I would need that now, before the first contribution. After I receive filled one I can merge any and all contributions across projects, so it is just one time hassle.
The most common way to do this is to print, fill & sign, scan (cell phone photo is fine), email to info at fasterxml dot com.

Looking forward to merging this fix, thank you again for contributing it!

[philleonard]

Thanks, contributor agreement has been sent your way.

[cowtowncoder]

Thank you again -- I merged this, and will merge in 2.10, do some light touch up.

In future it might be neat to simplify the process too, but first things first.
