Added a new extra strict RESTRICTED_TLS configuration inspired by [Google Cloud’s similar policy][googlecloud_ssl_policy]. It is appropriate when both the host platform
(JVM/Conscrypt/Android) and target webserver are current.

##### RESTRICTED_TLS cipher suites

 * TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
 * TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
 * TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
