Admin filter objects

Admin filter objects implements core.IAdminFilterObjects interface.

type IAdminFilterObjects interface {    WithTransaction(handler func(afo1 IAdminFilterObjects) error) error    LoadDataForModelByID(ID interface{}, model interface{})    SaveModel(model interface{}) error    CreateNew(model interface{}) error    GetPaginated() <-chan *IterateAdminObjects    IterateThroughWholeQuerySet() <-chan *IterateAdminObjects    GetPaginatedQuerySet() IPersistenceStorage    GetFullQuerySet() IPersistenceStorage    SetFullQuerySet(IPersistenceStorage)    SetPaginatedQuerySet(IPersistenceStorage)    GetUadminDatabase() *UadminDatabase    GetCurrentModel() interface{}    GetInitialQuerySet() IPersistenceStorage    SetInitialQuerySet(IPersistenceStorage)    GenerateModelInterface() (interface{}, interface{})    RemoveModelPermanently(model interface{}) error    FilterQs(filterString string)    Search(field *Field, searchString string)    SortBy(field *Field, direction int)    FilterByMultipleIds(field *Field, realObjectIds []string)    GetDB() IPersistenceStorage    GetLastError() error}

Right now uadmin supports only objects that stored in database or elasticsearch and we use corresponding go package to interact with storage. Later on we want to provide implementations for the objects stored in NoSQL, like Mongo, etc
