2.4.1
Adding DB liveness checks, with 2 new optional environment variables (should help fixing #172):
SHHH_DB_LIVENESS_RETRY_COUNT: This variable manages the number of tries to reach the database before performing a read or write operation. It could happens that the database is not reachable or is asleep (for instance this happens often on Heroku free plans). The default retry number is 5.SHHH_DB_LIVENESS_SLEEP_INTERVAL: This variable manages the interval in seconds between the database liveness retries. The default value is 1 second.
Remove support of FORCE_HTTPS. Shhh relies on status codes and most servers should implement https by default.
Adding more tests to have better coverage.
Fixing a few other bugs.
