Changes in SegConfig and AppConfig Classes

Depending on parameters of the Partition's get_segment() algorithm some SegConfig and AppConfig classes may be returned partially initialized, e.g. one can get a tree of segments without applications or initialized up to certain level of inclusion. Also, if segment is disabled, it has no applications initialized. A call of a method returning details of such segments may give incorrect data (such as reference on uninitialized object, e.g. get_controller() of segment with no applications initialized), if status of the segment's initialization and enabling is not checked explicitly.

It was decided to throw an exception in case if user tries to access uninitialized data. In particular:

Schema Changes

Remove RM_Computer_Resource and ComputerParameters classes, and made other relevant changes caused by re-implementation of the ResourceManager and it's configuration database simplification.
