Contains classes and interfaces for working with proxies.
ApnsClients will connect to an APNs server directly by default, they may
optionally be configured to connect through a proxy by setting a
ProxyHandlerFactory via the
ApnsClientBuilder.setProxyHandlerFactory(ProxyHandlerFactory) method. Proxy handler
factory implementations are provided for HTTP, SOCKS4, and SOCKS5 proxies.
