Bug - Failing Apache Cassandra 3.9 tests on CI

[hhandoko]

Expected Behaviour

CI tests on Apache Cassandra 3.9 should pass.

---

Actual Behaviour

CI tests on Apache Cassandra 3.9 in Travis started to fail recently, first identified in PR #25. Exact error message is:

...
shouldHaveDefaultConfigValues(com.builtamont.cassandra.migration.config.ClusterConfigurationTest)  Time elapsed: 0.007 sec  <<< FAILURE!
java.lang.AssertionError: 
Expected: is "localhost"
     but: was "127.0.0.1"
...

One possible cause is due to coercion of localhost input string to InetAddress type and back.

---

Steps to Reproduce

Run the integration test against the latest Apache Cassandra version (3.9).

As mentioned in #25 , this could be a side effect of the test setup (which passes 127.0.0.1) as part of the contact points system property value.

Provided a workaround to accept 127.0.0.1 for now, will refactor unit tests to clear and restore existing system properties variable as part of #28 .
