Autoconfigure ReactiveGridFsTemplate with MongoProperties.getGridFsDatabase()

[m-prati]

Using ReactiveGridFsTemplate I noticed that it is always user the main database, even if GridFsDatabase is specified.
I've adopted the workaround of defining my Bean

@Bean
public ReactiveMongoDatabaseFactory reactiveMongoDatabaseFactory(
   MongoProperties properties, MongoClient mongo) {
       String database = StringUtils.firstNonBlank(
         properties.getGridFsDatabase(), 
         properties.getMongoClientDatabase());
    return new SimpleReactiveMongoDatabaseFactory(mongo, database);
}

And I think this can be a useful solution for standard autoconfigure of ReactiveGridFsTemplate in
org.springframework.boot.autoconfigure.data.mongo.MongoReactiveDataAutoConfiguration file

@mp911de @christophstrobl what would you recommend please?

Given MongoProperties.gridFsDatabase exists, it's a bit odd that the imperative and reactive part behave in a different way selecting the database to use. Decorating the ReactiveMongoDatabaseFactory the way it's done with GridFsMongoDbFactory in MongoDbFactoryDependentConfiguration seems to be a good approach.

Thanks very much, @christophstrobl.
