Support project level mapreduce queue config

We have a lot of cubes in our compay , and for that we categorize cubes into diffent project based on user groups .

We want this cubes to use diffent mapreduce queue . Although cube-level mapreduce queue config can meet our demands , we need to set up mapreduce queue for each cube. That's a lot of work.

Now  weed need a project-level mapreduce config , cube can use different queue for different project.
