[erlang-questions] TLS cipher suite with Galois Counter Mode (GCM)

We're using RabbitMQ and now have a request for supporting the following
cipher suites:
    TLS_RSA_WITH_AES_128_GCM_SHA256 (0X009C)
    TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256  (0XC02F)
    TLS_DHE_RSA_WITH_AES_128_GCM_SHA256 (0X009E)
    TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256 (0XC02B)

However, if we use the following commands from the Erlang CLI we don't see
these cipher suites:

    io:format("~p", [ssl:cipher_suites(openssl)]).
    io:format("~p", [ssl:cipher_suites(erlang)]).

So how can we make these cipher suites available to Erlang.... and then
RabbitMQ that runs on top of Erlang?
