Test Existing QB Validation Errors

[robons]

validation tests (do not use the info.json interface to set these tests up, use the internal common model). Use the utils.qb.cube.validate_qb_component_constraints(...) method to perform validation in these tests.

• Define a cube with no dimensions. Ensure that validation yields a suitable warning.
• Define a cube with a QbSingleMeasureObservationValue with a unit defined. Also define a QbMultiUnits column. Only one of these should be defined; ensure that validation yields a suitable warning.
• Define a cube with a QbSingleMeasureObservationValue but do not provide a unit. Do not define a QbMultiUnits column. A unit should be provided in one of these locations; ensure that validation yields a suitable warning.
• Define a cube with more than one QbMultiUnits columns. Only one should be defined; ensure that validation yields a suitable warning.
• Define a cube with more than one QbObservationValue columns. Only one should be defined; ensure that validation yields a suitable warning.
• Define a cube with a QbMultiMeasureObservationValue, but do not define a QbMultiMeasureDimension; ensure that validation yields a suitable warning.
• Define a cube with a QbMultiMeasureObservationValue, and define more than one QbMultiMeasureDimension. Only one should be defined; ensure that validation yields a suitable warning.
• Define a cube with a QbSingleMeasureObservationValue and also define a QbMultiMeasureDimension. These types are incompatible; ensure that validation yields a suitable warning.
