Specifying socket options

[ivtu]

Hello,
I am using Cassandra 3 cluster (5 machines) and 3.1.0 version of your driver.
It seems that we cannot specify other values for socket options, because in SessionHolder I see only next:
builder.withSocketOptions(new SocketOptions().setKeepAlive(true));

Can we somehow get new version with possibility to specify:

1. connectTimeoutMillis
2. readTimeoutMillis
3. tcpNoDelay

Thanks in advance.
