* Moved rally.task.scenarios.base -> rally.task.scenario
- Shorter imports and simpler structure of tree
- Unified with other plugin bases
* Add rally.task.atomic module
- We will use atomic actions in both scenarios and context
this is first step of unification
- Module has only links to method and atomic action context
with new names. So we will change all plugins but won't
touch atomic actions at this patch (to reduce amount of
LOC in this patch)
- Next step is to move and unify atomic action code for
scenarios and contexts
* Rename rally.task.scenario.scenario to rally.task.scenario.configure
scenario.scenario is unclear and not aligned with other plugin
types where configure() method is used for the same purpose
* Add shortcut rally.plugins.openstack.scenario.configure
so there is no need to import rally.plugins.openstack.scenario
and rally.task.scenario modules
* Fix all unit tests & docs
