This PR addresses #1463. This PR adds a new metric
xrootd_cpu_utilization. This metric is calculated from the summary statistics provided by XRootD. The CPU utilization is calculated via the following: (CPU time used) / (Wall time elapsed). The CPU time used is calculate by calculating the delta between the last amount of CPU time used and the current cpu time used. The wall time elapsed is calculated as the difference between the current time and the last time we received a summary statistic.
