This allows us to create checkpoints of the embedding tables in SSD. Later, these checkpoints are used by the checkpointing component to create a checkpoint and upload it it to the manifold In this diff: We are adding all the helper functions to create folder structures in SSDs for storing the rocksDB checkpoints Differential Revision: D75489819

It consists of the file paths to the checkpoint of all shards. When creating KVTensorWrappers, we use the same checkpointHandle object 1. Creating CheckpointHandle class 2. Adding the definition for CheckpointHandle constructor 3. Adding CRUD functions for CheckpointHandle 4. Connecting CheckpointHandle to EmbeddingRocksDB entity Differential Revision: D75489827
