:param context: ContegoserverContext of the query.
:param model: Model to query. Must be a subclass of ModelBase.
:param args: Arguments to query. If None - model is used.
:param read_deleted: If not None, overrides context's read_deleted field.
Permitted values are 'no', which does not return
deleted values; 'only', which only returns deleted
values; and 'yes', which does not filter deleted
values.
:param project_only: If set and context is user-type, then restrict
query to match the context's project_id. If set to
'allow_none', restriction includes project_id = None.
