Add PuppetDB Jetty thread metrics

Jarret Lavallee · Jarret Lavallee · commit 9cea60cf0d47 · 2021-06-01T14:57:31.000-06:00
Prior to this commit, there were no metrics around the jetty thread
pool. This commit adds additional metrics to collect the jetty
queuedthreadpool metrics. This allows for looking at the jetty thread
usage in PuppetDB.
