Implement SDK support for Topic Auto-Partitioning Settings

[Eistern]

This PR introduces support for configuring and describing auto-partitioning settings for YDB topics within the Java SDK. Users can now define the auto-partitioning strategy and its associated parameters (stabilization window, utilization thresholds) when creating or altering topics. These settings are also reflected in the TopicDescription returned by describeTopic.

Key Changes:

• Auto-Partitioning Configuration:

  • Added AutoPartitioningStrategy enum (DISABLED, SCALE_UP, SCALE_UP_AND_DOWN, PAUSED) to define the auto-partitioning behavior.
  • Introduced AutoPartitioningWriteStrategySettings (for createTopic and describeTopic) and AlterAutoPartitioningWriteStrategySettings (for alterTopic) to manage:
    • stabilizationWindow
    • upUtilizationPercent
    • downUtilizationPercent
  • These settings are now part of PartitioningSettings and AlterPartitioningSettings respectively.

• SDK Method Updates:

  • createTopic: Can now specify initial auto-partitioning settings via CreateTopicSettings -> PartitioningSettings.
  • alterTopic: Can now modify auto-partitioning settings via AlterTopicSettings -> AlterPartitioningSettings. AlterAutoPartitioningWriteStrategySettings allows for partial updates (e.g., changing only the stabilization window).
  • describeTopic: TopicDescription now includes the currently configured auto-partitioning strategy and write strategy settings.

• New Classes:

  • tech.ydb.topic.settings.AutoPartitioningStrategy
  • tech.ydb.topic.settings.AutoPartitioningWriteStrategySettings
  • tech.ydb.topic.settings.AlterAutoPartitioningWriteStrategySettings

• Refactoring & Improvements:

  • Implemented equals() and hashCode() methods for various topic description classes (TopicDescription, PartitioningSettings, Consumer, ConsumerDescription, ConsumerPartitionInfo, MultipleWindowsStat, PartitionInfo, PartitionStats, SupportedCodecs, TopicStats, OffsetsRangeImpl) to improve data integrity and simplify comparisons, particularly in tests.

• Testing:

  • Added a new integration test step07_alterTopicWithAutoPartitioning to verify the alterTopic functionality with new auto-partitioning settings.
    • Note: This test is currently marked @Ignore as the auto-partitioning feature via alterTopic requires YDB server version 25.1 or newer.
  • Minor fix in existing test (e.g., msg.commit().join())
