Logic to log vertex exclusion only once does not work correctly

As part of daeb4b6559f0d26b1b0f23be5e8230f895b0a03e we wanted to log vertex exclusion only once. This logic does not work because the vertices without busy time are excluded in memory for every run. So we print "No busyTimeMsPerSecond metric available for {}. No scaling will be performed for this vertex." for every run.
