scheduler_perf: run with -v=0 by default

Browse Source 
This provides a mechanism for overriding the forced increase of the klog
verbosity to 4 when starting the apiserver and uses that for the scheduler_perf
benchmark. Other tests run as before.

A global variable was used because adding an explicit parameter to several
helper functions would have caused a lot of code churn (test ->
integration/util.StartApiserver ->
integration/framework.RunAnAPIServerUsingServer ->
integration/framework.startAPIServerOrDie).
