Benchmarking loading JSON file vs YML file (#2897)

* Fix#2851 Add namespace to benchmark rake task to add other tasks

* [Fix:2851] Add rake task to compare loading translation times with JSON vs YML

* [Fix:2851] Add es-MX.json file

* [Fix:2851] Use JSON.load_file method in benchmark since that is the method that i18n is using

* [Fix:2851] Address PR comments. Moved JSON file into test directory
