Added sorting to all controller classes to get many method, sorting represented by 2 params:

• sort (field name)
• order - sorting direction (supports only asc or desc)

Additionally were completed following features:

1. Sorting was added to EFModelManager and sort represents model property name therefore all Manager classes that works with EF as DataContext have builtin sorting
2. Sorting was implemented in demo project in EdgeDbManager (edgedb) in EqlResolver class, see
