collectionPrefix for MongoDB Job repository

[gyuyeol]

Expected Behavior

EnableMongoJobRepository should accept a collectionPrefix so that a prefix can be specified for the MongoDB collections used by the job repository.

Current Behavior

At the moment this feature does not exist. Adding it would mirror the existing tablePrefix option in EnableJdbcJobRepository, enabling multi‑application support, environment isolation, and easier management of the underlying collections.

Context

A workaround could be implemented by modifying MongoJobRepositoryFactoryBean and a few DAO classes. However, it would be preferable to provide this functionality as a built‑in feature.
