DnsClient implementation relies on building multiple instances of DnsNameResolver which by default instantiate a FastThreadLocal query server address stream. As side effect this expand the FastThreadLocal entry size which can be considered as a leak.
DnsNameResolverBuilder now accepts a query server address stream instance to override the default FastThreadLocal instance, to avoid this (slow but steady) leak.
