Adjust V level for scheduler messages

The "Combined requested resources" message becomes excessive as
the cluster fills up, drop it down to V(2)
Put an explicit V(2) on the only other scheduler Infof call that didn't
have V specified already.

These messages are only useful if you want to debug a particular
scheduler assigment, and they are extremely verbose-- they each print
out a line per host per assignment. Let's try to keep our log messages
linear in the number of assigments.
