* Add more info about basic entities in rally, add samples
* Fix wrong multiline :param: handling
* Fix "rally info BenchmarkScenarios" output so that it contains
no base classes with no scenarios
* Sort entity tables (BenchmarkScenarios/DeployEngines/...) by names
* Enable search for SLA by config option name (not only by class name)
and print this config option name in "rally info SLA"
* Fix SLA desciption in the basic "rally info" call
* Rename "rally info DeployEngines" -> "rally info DeploymentEngines",
but leave an alias (so that "DeployEngines" still works)

excessive CLI arguments
* Other cosmetic improvements
