When using Spring Cloud Vault to generate credentials for a MongoDB instance, it's impossible to use the spring.data.mongodb.uri property, as setting that causes the username/password fields to be ignored.

This can normally be worked around by just specifying the host/port/database/etc, but that's not as nice, and still doesn't let you specify a different protocol, such as 'mongodb+srv', which is very useful when deploying under Kubernetes.

What would be nice is to have the username/password (if specified), injected into the uri.

The mongodb driver the 2.1 branch is using doesn't actually support mongodb+srv, but the 2.2 branch does.

I don't see an alternative way to specify the protocol, but I could be missing something.
