JBCACHE-1442 "setData()" call

[genman]

This is an API extension to Cache, a new "setData" call, which basically is the same as the old "putData(Map, boolean erase)" call.

I would like some people's input on this patch.

I'd like to see this in post 3.0, if possible, for my own project.

A bit like Map.replace()?

Cache.getNode(Fqn).replaceAll() would be one possible API solution except if the node doesn't exist you get a NPE.

Maybe there should be a Cache.createNode(Fqn) API which created or returned the existing node at the FQN, without loading it?
