NEWTS-111: OpenNMS Integration with cloud-hosted Cassandra

[jeffgdotorg]

• Updated Cassandra driver to v3.8.0
• Added accessors for cloudConnectBundle
• Hooked up existing username and password as client-ID and client-secret when a cloud-connect bundle is configured
• Updated logging

Changes look good. I think we may also need to bump the version of cassandra-unit that is used for the tests to pass.

We also need to understand any changes to the transient dependencies made by upgrading the Cassandra driver as this may impact which versions of OpenNMS we can pull this into.

Nice, it's green! I can help take a look at comparing the dependency changes.

Transient dependencies look good - only a new dependency on com.fasterxml.jackson.core:jackson-databind:jar:2.5.4:compile - version if Netty remains unchanged.

Just double-checked deps after fixing tests and bumping to 3.11.0, and it looks like in addition to jackson-databind, it ends up bumping netty and adding a few things as well, but on the opennms side we're actually already using/overriding newer versions anyways. We'll just want to double-check what gets pulled in before and after, but since this would go to develop it should be OK.
