safatshahin dfed4fd040 MDL-71516 core_question: Qbank api implementation
This commit implements the qbank api so that any plugin
can implement its own question bank. This api currently
works parallely with the moodle core classes and the
added qbank in the core, means the moment a plugin
is installed, that object is replaced with the object
from the plugin instead of core, which means the api
has flexibility till the plugins are integrated and the
plugins can be integrated in any order.

All the old classes are still there and not deprecated
as there is a different tracker for the changes to the
quiz and another tracker for class deprecation and
class renaming. Core question units tests are pointing
to the new api structure but the classes are pointing
to the location related to the plugin availability.
