* in case MISTRAL_REST_ACTION we add Mistral-specific
headers, in case REST_ACTION - we are not.
* new class for this type of action is unnecessary,
all of these are Rest, only properties can be edited
in factories methods

* Access to new task properties:
input, onSuccess, OnError; any task property
* 'dependsOn' is renamed to 'requires' and returns dict object
which contains conditions of task transition.
DSL can be defined either:
task3:
requires: [task1, task2]
or:
task3:
requires:
task1: condition1 (or empty)
task2: condition2 (or empty)

* Moved iethods start_workflow_execution and convey_task_result into
abstract engine
* Refactored existing local engine unit tests
* Added simple unit tests for scalable engine
* Minor cosmetic changes (imports, blank lines)

* Action definition was combined in actions module
* workflow from both single and scalable engines were deleted
* task from single engine was deleted
* unit test 'test_workflow' was deleted due to deleting workflow
* minor fixes to single engine
Next step will be extracting and combining common parts
of scalable and single engine.

* New engine for running workflow (w/o rabbit)
* Engine constructs a workflow
* REST API action
* AMQP action (not finished)
* Task and execution state update
* Added unit tests for this engine

* Workbook events creation is now called from a REST controller rather
than from DB API. This is more proper place (level of abstraction).
* Fixed workbook definition controller and evets tests.
Change-Id: Ib17d0b0dae614c474c161cd12ecbb1b05aea74a8
* Simple server
* expose one endpoint - /tasks
* recieve correct signal from mistral
about task execution, log 'task N started,
task N finished'
* logging
