Walkthrough

This PR extends EloqStore's cloud storage capabilities by adding a new source file to the build configuration and introducing three configuration flags to manage cloud upload batching, request concurrency, and threading parameters.

Changes

Cohort / File(s)	Summary
Build Configuration store_handler/eloq_data_store_service/build_eloq_store.cmake	Adds cloud_storage_service.cpp to ELOQ_STORE_SOURCES list for compilation into eloqstore library.
Configuration Management store_handler/eloq_data_store_service/eloq_store_config.cpp	Introduces three new global configuration flags (eloq_store_max_upload_batch, eloq_store_max_cloud_concurrency, eloq_store_cloud_request_threads) and corresponding fields in EloqStoreConfig struct initialized via constructor using flag-or-config pattern. Note: Duplicate initialization blocks detected for the same three fields.
Submodule Reference store_handler/eloq_data_store_service/eloqstore	Updates eloqstore submodule pointer from bafb377d7061e315b01f86ba79a0eae81a3adfa1 to cd987d107cf6684e6cd031e5bb6c8a70479f4668.

Poem

🐰 A cloud storage quest we now begin,
Three flags dance in—concurrency, threads spin!
With batching and threading, so swift and so keen,
The EloqStore now soars to clouds unseen! ☁️✨

In `@store_handler/eloq_data_store_service/eloq_store_config.cpp`:
- Around line 130-138: The help text for the flag DEFINE_uint32 named
eloq_store_max_upload_batch is misleading (it says "concurrency"); update its
description to reflect that it controls the maximum upload batch size per core
(e.g., "EloqStore max upload batch size per core") and ensure consistency with
nearby flags DEFINE_uint32(eloq_store_max_cloud_concurrency) and
DEFINE_uint32(eloq_store_cloud_request_threads) so operators see clear, distinct
meanings for batch size vs concurrency.
