MultiTenant Implementation

Introduction

I implemented the MultiTenant support by:

1. Extending SimpleMongoRepository to add the missing EntityInformation JavaType to extract the @MultiTenantField value from the Entity.
2. Extending MongoTemplate to add the logic to add the @MultiTenantField value to the query and save operations.

⚠️ Unknown behaviour

I implemented those methods that we needed in our product. As we are using more functionality, we detect the missing methods, and we add them to the library.

Current implementation
