Disable dns caching in reaper #1297

Now cassandra-reaper used in k8ssandra-operator project, due to running cassandra in k8s, ips of nodes are ephemeral(they can changed after restart node). Currently reaper resolved only one time k8ssandra all-dc-pods-service and after restart cassandra, reaper cant connect to previous cached contact points ips

We suggest add advanced.resolve-contact-points = false option and always resolve dns on new connection

Option advanced.resolve-contact-points = false supported only in cassandra-driver 4.x versions. For 3.x version we use this solution .builder() .addContactPoint { InetSocketAddress.createUnresolved(config.host, config.port) } .withCredentials(config.credentials.login, config.credentials.password) .build()
