MDL-71696 core_question: Changes for versioning

Browse Source 
This commit adds the changes in questiontype base
to work with new question tables and the new structure in the
databse. Also needed for versioning.
This implementation will also introduct the question status
which allows a question to be in draft and ready status.
I also introduces changes to the base view where it shows
the latest version of the questions. The view of versions
for a question is not implemented in this commit.
This implementation will also introduce changes in the core
qtype plugins to support versioning and the changed
db schema.
