Ensure that the MQTT Client connects to servers eventually

If the server is not available then we should use the reconnection delay to wait and then reconnect.

Make the sensiNact build more CI friendly

Since Maven 3.5.0 poms have had the ability to be [CI-friendly](https://maven.apache.org/maven-ci-friendly.html) allowing a more flexible approach to releasing without the need to edit POM files. This also impacts the creation of our feature files, which can now flexibly alter the versions of the bundles they deploy to match what's being built in by CI. The end result should be a much simpler time when we want to tag or release any particular commit.
