chore(benchmark): wire excludedRegionsList into Cosmos*RequestOptions

[jeet1995]

Summary

Plumbs the existing excludedRegionsList benchmark config field through every per-request Cosmos*RequestOptions construction site in the vanilla async/sync workloads of azure-cosmos-benchmark. Without this, configuring excludedRegionsList had no effect on the actual request paths.

Note: CosmosClientBuilder also exposes excludedRegionsSupplier(Supplier<CosmosExcludedRegions>) for client-wide configuration. This PR takes the per-request approach to keep the change localized to the request-options layer; a follow-up can switch to the client-level supplier if preferred.

Changes

TenantDefaultConfig.java — mirrors preferredRegionsList:

• New excludedRegionsList field with @JsonProperty
• New getExcludedRegionsList() that splits the comma-separated value (returns null when empty)
• Inheritance line in applyTo(TenantWorkloadConfig)

Wired setExcludedRegions(workloadConfig.getExcludedRegionsList()) into:

• AsyncBenchmark — CosmosBulkExecutionOptions (pre-population bulk path)
• AsyncQueryBenchmark — CosmosQueryRequestOptions
• AsyncQuerySinglePartitionMultiple — CosmosQueryRequestOptions in constructor
• AsyncReadBenchmark — switched to the readItem overload accepting CosmosItemRequestOptions
• AsyncReadManyBenchmark — switched to the readMany overload accepting CosmosReadManyRequestOptions
• AsyncWriteBenchmark — CosmosItemRequestOptions on both createItem branches
• SyncBenchmark — CosmosBulkExecutionOptions (pre-population bulk path)
• SyncReadBenchmark — hoisted inline CosmosItemRequestOptions to a local
• SyncWriteBenchmark — CosmosItemRequestOptions on both createItem branches

Out of scope (intentionally not modified)

• AsyncMixedBenchmark, ctl/AsyncCtlWorkload, ReadMyWriteWorkflow, all encryption/* workloads — deferred.
• DocDBUtils, BenchmarkHelper retry path, CosmosMetricsReporter — not workload paths (management metadata, retry helper, reporter infra).

Verification

• mvn -f sdk/cosmos/azure-cosmos-benchmark/pom.xml -DskipTests -am compile — passes
• mvn -f sdk/cosmos/azure-cosmos-benchmark/pom.xml checkstyle:check spotbugs:check — passes
• Grep audit of new Cosmos*RequestOptions / new CosmosBulkExecutionOptions in src/main confirms every remaining occurrence is either followed by setExcludedRegions(...) or is in the intentionally-skipped list above.

Pull request overview

Wires the existing excludedRegionsList benchmark config field into per-request Cosmos*RequestOptions across vanilla async/sync workloads in azure-cosmos-benchmark. Excluded regions are a per-request SDK feature, so configuring this field previously had no effect.

Changes:

• Add excludedRegionsList field, getter, and applyTo(...) inheritance in TenantDefaultConfig (mirroring preferredRegionsList).
• Call setExcludedRegions(...) on CosmosItemRequestOptions, CosmosQueryRequestOptions, CosmosReadManyRequestOptions, and CosmosBulkExecutionOptions across the vanilla async/sync workloads.
• Switch AsyncReadBenchmark and AsyncReadManyBenchmark to overloads that accept request options.
