big reorg: prepare for generalization

Try to split into three separate components -> controller, tester,
and 'tasks' (postgresql-tasks in our case).  The controller
component is the main part which is able to run the task remotely.
Tester is more-like library for 'tasks' component (should be
reusable on the raw git level).

* controller: Almost separated component.
* postgresql-tasks: Likewise.
* tester: Likewise.
