SOLR-15056 change circuit breaker metric

Starting work on this change. Should that be against branch_8x?

https://issues.apache.org/jira/browse/SOLR-15056 <https://issues.apache.org/jira/browse/SOLR-15056>

OK, I’ll do it against master. We’d love to see it in an 8.x release, though.
This would protect against the major Solr outages we’ve had in the past
few years.

A question for someone who knows the Java metrics stuff better than I do:

Is it OK to use com.sun.management.OperatingSystemMXBean instead
of the java.lang.management version? getSystemCpuLoad() is only in the
former. The current code uses java.lang.management.OperatingSystemMXBean.

Glad to see you contributing Walter!

Unless you know it only applies to 8x, you should branch against master.
