Lots of work on the test-suite in this commit including:
- Rename ServiceTestBase to ActiveMQTestBase
- Make AddressSettings fluent
- Remove unnecessary tearDown() implementations
- Use ActiveMQTestBase.create*Locator() instead of
ActiveMQClient.createServerLocator*(..)
- Use fluent ServerLocator methods
- Make sure all ActiveMQServers.newActiveMQServer invocations
are surrounded with addServer() where appropriate
- Create a few example tests to be references from hacking-guide
- Update hacking-guide with more info on writing tests
- Refactor config creation methods in ActiveMQTestBase
