This PR adds a configurable retry mechanism when connecting to a MongoDB instance.
Motivation
When running MailHog with MongoDB In a containerized environment, it is likely that starting the MongoDB service needs longer than starting MailHog. In this case, MailHog does a fallback to its in-memory storage without further notification. This is probably not what you want when running a MongoDB.
Description
This PR adds three new configuration options:
MongoRetriesMongoRetryIntervalInMemoryFallbackWhen having configured MongoDB, MailHog will execute
MongoRetriesattempts for a successful connection. Between each attempts it will wait forMongoRetryIntervalseconds. If the connection is not successful, it will either exit (InMemoryFallback = false) or use in-memory storage (InMemoryFallback = true).
