Dynamic collection name

I would like to prefix our collections by the environment name
- dev
- staging
- etc..

I would like the annotation `@Document(collecionName = "test")` to be dynamic
We could either use [spring expression language](https://docs.spring.io/spring-framework/docs/3.0.x/reference/expressions.html) for that.

Is this something you would consider to add?

Do you know if there is another way to set the collection name dynamically?

Start by locating how the @Document collectionName value is read and how collection names are tested. Review whether Spring Expression Language can be supported for this annotation, then define completion as environment-dependent collection names working reliably with coverage for the proposed syntax.
