[FLINK-4544] Refactor old CPU metric initialization
This PR refactors the old CPU metric initialization code to no longer rely
on reflection.
Instead it eagerly casts the `OperatingSystemMXBean` returned by
`ManagementFactory#getOperationSystemMXBean()` to
`com.sun.management.OperatingSystemMXBean`. Should this succeed it is now
guaranteed that the gauge will not throw a `ClassCastException` since it
doesn't have to cast anything; if it fails a dummy Gauge is registered that
returns -1 in order to retain existing behavior.
