Portable API won't be a part of 1.4 release

[Denis Magda]

Igniters,

As you know GridGain contributed this API to Apache Ignite project and
the API became available for developers several merges ago :)

However, it makes sense to revisit/rework this API removing design
issues inherited from the time when it was a part of GridGain. That's
why Portable API won't be a part of public API in upcoming 1.4 release.
