• Validate that docker image names include a tag on creation

• By default, use docker machine name from DOCKER_MACHINE_NAME environment, or default if it exists
• Allow container ports to map to a fixed port on the host through use of the FixedHostPortGenericContainer subclass of GenericContainer

• Improve documentation and logging concerning discovery of Docker daemon

• Rename container getIpAddress() method to getContainerIpAddress() and deprecate original method name.
• Rename container getHostIpAddress() method to getTestHostIpAddress()

• Resolve thread safety issues associated with use of a singleton docker client
