avoid burst cache hits by using nsvs instead of ns_cache for secret token cachingThe problem with the prevision version was that ns_cache has no equivalentto nsv_array to get in an atomic fashion all key value pairs from the cache.thefore, for the per-thread caching, a tight loop was used processingthe result of ns_cache_keys. If this was necessary in a high number ofthreads, higher lock times were possible (~100ms). The new versionshould not face this problem.
