OF1.4: Cannot set importance for a flow

[alexandravlad]

Tested with Luxoft's Twister framework, OF1.4
Create and insert a flow that has the importance = 6
Output from LINC console:

Test result: Switch seems to accept the specific flow, but when get flow stats from switch, the importance is equal to 0 instead of 6.
