refactor(LSM index): update compaction logic and introduce new config…

[robfrank]

This pull request introduces a new TextSupplier utility to provide random English text for use in test data, and integrates it into the performance test suite. Additionally, it refactors the container directory structure and schema for more robust test setup and data modeling. The main changes are grouped below.

Test Data Generation and Integration:

• Added the new TextSupplier class to generate random English text, sourced from a word list, for use in test entities. (e2e-perf/src/test/java/com/arcadedb/test/support/TextSupplier.java)
• Updated all usages of DatabaseWrapper in performance tests to accept and use a TextSupplier instance, ensuring photo descriptions are populated with random text. (SingleLocalhostServerSimpleLoadTestIT.java, SingleServerLoadTestIT.java, SingleServerSimpleLoadTestIT.java, DatabaseWrapper.java) [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13]
• Modified the photo schema to include new name and description properties, and added a full-text index on description. (DatabaseWrapper.java)

Test Container and Directory Structure Refactor:

• Refactored container directory creation and cleanup to use new backup and log directories, and updated mount paths for containers accordingly. (ContainersTestTemplate.java) [1] [2]
• Added initialization of TextSupplier in the test container setup template for consistent access across tests. (ContainersTestTemplate.java) [1] [2]

Configuration Improvements:

• Added a new environment variable arcadedb.commitLockTimeout=10000 to ArcadeDB container startup for improved reliability during tests. (ContainersTestTemplate.java)

Minor Cleanups:

• Improved import statements for clarity and consistency in several files. (ContainersTestTemplate.java, LSMTreeIndex.java) [1] [2]
• Corrected formatting in TypeIdSupplier.java.

These changes collectively improve the realism and robustness of the performance test suite by generating more realistic test data and ensuring container environments are consistently prepared and cleaned up.
