New candidate JEP: 429: Extent-Local Variables (Incubator)

[Zheka Kozlov]

Just out of curiosity: why was a static where() method chosen? An instance
method seems more natural:

PRINCIPAL.where(principal).run(...)
vs.
ExtentLocal.where(PRINCIPAL, principal).run()

Also, a couple of notes regarding Javadoc:

   1. Two methods runWithBinding() and callWithBinding() are mentioned in
   the description. But ExtentLocal doesn't have such methods. It only has
   three overloads of where().
   2. The code example doesn't use a code snippet. It uses the old HTML
   formatting.
