Defining a workflow start task
We need to be able to define a workflow start task write in the model (and respectively in DSL). In practice, it doesn't make a lot of sense to start with a random task because real workflows involve data processing and hence all actions need to be taken in a certain order to prepare all data for a certain workflow task.
As a part of this BP we need to get rid of Execution "task" parameter when we start a workflow (in all the models, API, python client and CLI).

Refactor test_engine to not rely on start_task
Please deprecate this for a bit at the python client level otherwise solum might end up
getting broken. Also we need a way of communicating such things (api changes) to the users. Normally if you remove something from an API you need to bump the major version number. That might be a bit drasitic but I think at least deprecating it and removing it later is reasonable. So on the client start printing out a warning that
soon this start_task will be ignored then later remove the parameter.
Once you have a real user, it stops becomming a PoC and you need to version properly.
