Snapshots feature refactor

[AnnaPaolaMusio]

The C++ implementation of the KVS module has been modified in terms of snapshot behavior.

1. Removal of snapshot_rotate
   The snapshot_rotate function has been completely removed from the C++ implementation. Snapshot management is no longer automatic and requires an explicit call to the snapshot_create() function.

2. The flush() function no longer automatically creates snapshots.
   In the previous behavior (still valid for RUST) flush() persisted the data and called snapshot_rotate() to automatically create a new snapshot. Now flush() now only persists the current state of the KVS to disk.

3. Implementation of snapshot_create API
   The new snapshot_create() function has been implemented, allowing for the explicit creation of snapshots in the first available slot.

4. Implementation of snapshot_delete API
   The snapshot_delete() function has been implemented to explicitly remove a specific snapshots by ID.

5. Update to snapshot_count and snapshot_restore.

6. A new component requirement has been introduced, according to the new behaviour of the snapshot_create.
