Moved end to end tests to integration tests

	Speed up integration tests by combining them into one cluster start/stop
Temporarily @Ignore Scanner, pending fix for #304

	I moved the end to end tests into the intergration section.
	To run them use mvn test-compile failsafe:integrion-test
	I also slipped in random memstore flushing as an experiment.
	I vastly simplifed the end to end minicluster and only start it
	only once.
