Add Gson benchmarks

[m0mus]

The goal is to compare JSONB-RI with Jackson, Genson and Gson. Each benchmark test has to be created for all these frameworks with cold and warm engine. Cold means that the engine is created in the test and warm means that the engine creation and initialization is not a part of test.

This task is about adding Gson framework to the project and add Gson benchmarks for all current tests.
