Subject: [PATCH] Introduce jest for testing.

We are already using Mocha as testing framework but for some reasons
such as readability and convenience, we decided to use jest instead of
Mocha.

After this patch, ./bacardi test will run both of Mocha and jest.
Once we write test codes enough in jest, we will deprecate Mocha.
