Implement termination of worker threads. To achieve the goal so called
control queue has been introduced which is handled in Worker base class.
Once worker thread receives stop message it tries to kill itself. It is
possible to join a worker thread before deinit know thanks to a
semaphore given before thread termination.
Some improvements to the interface and implementation has been made
including state sanity checks. It is assumed that only service that owns
the worker is allowed to stop it, which allows not to consider code
reentrancy.
Worker destroying procedure has been updated in services that already
own workers.

* EGD-3087 WIP adding SMS Querry
* EGD-3087 Added query virtual interface on Service top layer
Service shouldn't implement query logic and should be proxying that.
additionally:
- small fixes in includes
- shared service db name same way as apps and event manager
* EGD-3087 Query - want to work on interface not on db
* EGD-3087 Query gluecode works fine. Our query in SMS search calls getBySMSQuery
Changes cut off before any potential orm interface layer

Till now there was no clear way to register hanlder for message in
Service, with this approach one can register function/lambda handler
for Message which encurages handling messages in functions rather than
in hudge switch cases.
With aproach like this our Messages resembe something between Command
and State pattern. In state pattern `Message` would be `Event` send,
whereas Service would be `Context`.
