If no custom I18NProvider is configured the log is polluted by INFO messages.

For example:

qtp925385170-53 2018-03-09 08:07:40 INFO [c.v.f.s.SpringInstantiator] - The number of beans implementing 'I18NProvider' is 0. Cannot use Spring beans for I18N, falling back to the default behavior

logged in https://github.com/vaadin/flow/blob/master/flow-spring-addon/src/main/java/com/vaadin/flow/spring/SpringInstantiator.java#L67

Besides that this is a good information I have the feeling this information should be logged only once. For applications that do not need internationalization it is rather annoying.

We adjust the logger for now.
