GA refactoring for better support of other DB engines

Registered by Illia Khudoshyn on 2013-09-26

Considerable part of guest agent code base (e.g. MySqlAppStatus) is now implemented as MySQL specific while it is actually rather generic. This BP is aimed to extract this generic part of code to separate classes/modules. It will make it much easier to implement support for other DB engines. This BP does not imply any changes in current functionality.

Code, common for Managers, is to be extracted to a mixin.
Application and ApplicationStatus instances accessed by Manager should be contained
in Manager instance, rather then being instantiated each time or retrieved as a singleton.
