Description of Changes

This PR sets the Sequelize dialect type for the queryGenerator and queryInterface.

Currently the sequelize instance in the queryGenerator and queryInterface uses the AbstractDialect which mean accessing the sequelize.options from inside these classes does not return the correct typed values.
