vbucket-seqno stats requests getting timed out during view queries

Test to reproduce:
view.viewquerytests.ViewQueryTests.test_employee_dataset_query_different_buckets,docs-per-day=500,sasl_buckets=4,standard_buckets=4

Note: This issue is opened to track the performance impact on view queries due to these timeouts.

Seeing lot of timeout errors in logs:
