If the new fair policy is at least as good as FIFO and we can afford to
remove round-robin, we can simplify the scheduler code by making the
scheduler to run queue relationship always 1:1 and remove some code.
Also, now that the FIFO policy is gone the tree of entities is not a FIFO
tree any more so rename it to just the tree.
