Modules: added state file for the shared dictionary.

A new optional state parameter is added for js_shared_dict_zone
directive. state parameter specifies a file that keeps the current state
of the shared dict in the JSON format and makes it persistent
across nginx restarts.

This closes #709 feature request on Github.
