Kotlin does have properties and we take advantage of them in OkHttp.

 * **Address**: certificatePinner, connectionSpecs, dns, hostnameVerifier, protocols, proxy,
   proxyAuthenticator, proxySelector, socketFactory, sslSocketFactory, url
 * **Cache**: directory
 * **CacheControl**: immutable, maxAgeSeconds, maxStaleSeconds, minFreshSeconds, mustRevalidate,
