Release Note:
A new Interface and a default implementation to convert and restore serializations of objects to strings.

Description

Storing arbitrary objects in the configuration has been discussed before in ~~HADOOP-449~~ and ~~HADOOP-1873~~. Although enabling such functionality has the risk of encouraging people to put big binary objects in the configuration, for some use cases passing objects to tasks is absolutely necessary.

This issue will track the implementation of a Stringifier interface which stringifies and destringifies objects. Using this implementation, developers can store objects in the configuration and restore them later.

Any thoughts ?
