Removed code smells

[Freya02]

Implementation Smells

1. Decompose Conditional
   Package: com.redis.om.spring.convert
   Class: MappingRedisOMConverter,
   Method: doReadInternal (code line 151)
   Cause of the Smell: The conditional expression entity!= null && instance != null && entity.hasIdProperty() is complex.

2. Extract Method
   Package: com.redis.om.spring.audit
   Class: EntityAuditor
   Method: processEntity (code line 25)
   Cause of the Smell: Long method processEntity

3. Introducing Explaining Variable
   Package: com.redis.om.spring
   Class: RedisModulesConfiguration
   Method: faceDetectionTranslator
   Cause of the Smell: confThresh is not a clear variable name.

4. Introducing Explaining Variable
   Package: com.redis.om.spring.cuckoo
   Class: CuckooAspect
   Method: addToCuckoo
   Cause of the smell : Complex conditional statement

5. Extract Method
   Package: com.redis.om.spring
   Class: RediSearchIndexer
   Method: findIndexFields
   Cause of the smell : Complex method smell.

Design Smells

1. Move method/field.
   Package: com.redis.om.spring.id
   Class: ULIDIdentifierGenerator

Description:
This refactoring technique involves moving a method or a field from one class to another to improve the organization and design of the code. In this case, the getSecureRandom method and the OsTools class were moved from the ULIDIdentifierGenerator enum to a new class named SecureRandomUtils. This makes the code more modular and separates concerns related to secure random generation from the main identifier generation logic.

2. Replace conditional with polymorphism
   Package: com.redis.om.spring.util
   Class: ObjectUtils

Description:
This technique involves replacing conditional statements (like if-else or switch) with polymorphic behavior, where each condition is represented by a separate class or method. The original code had a series of if-else statements to determine the appropriate GeoUnit based on the DistanceUnit.I introduced the DistanceUnitConverter interface, defining a common method (getGeoUnit) that represents the behavior of converting a DistanceUnit to a GeoUnit.Four concrete classes (MilesConverter, FeetConverter, KilometersConverter, MetersConverter) were created, each implementing the DistanceUnitConverter interface and encapsulating conversion logic for a specific DistanceUnit.A Map named converters is used to associate each DistanceUnit with its corresponding DistanceUnitConverter. This replaced the original if-else statements.Polymorphic calls to the getGeoUnit() method calls allows to dynamic dispatch to the appropriate converter based on the DistanceUnit.and other units.

3. Extract Class
   Package: com.redis.om.spring
   Class: RedisJSONKeyValueAdapter

Description:
The logic for processing references and versions has been moved to dedicated classes (ReferenceProcessor and VersionProcessor). This adheres to the Single Responsibility Principle by ensuring that each class has a single reason to change and is responsible for a specific aspect of the overall functionality.These refactoring changes aim to enhance the code quality, maintainability, and adherence to good design principles.

This PR seems pretty broken. Is this AI generated?

Hi, thank you for taking time out to review my PR.
This is not AI generated code, however some code smells were partially solved and thus some parts of code may have broken. I will solve them and raise a new PR. Thank you once again!
