SOLR-17744: Change default SOLR_JETTY_GRACEFUL value to false
Based on test failures noted in SOLR-17764, the implications of what this might
mean for some SolrJ users, and a lack of concensus on how to move forward, I'm
changing this defualt to minimize the risk of impact on users when upgrading

> Reviewing recent jenkins test failure metrics, I noticed that (Nightly) test
> ChaosMonkeySafeLeaderWithPullReplicasTest started failing ~60% of the time
> right around the time that SOLR-17744 was committed.
> Things i have observed:
> * Seeds from failing runs seem to reliably reproduce the failure
> ** These failures do *NOT* reproduce if i revert to just before SOLR-17744
> * Ad-hoc testing I've done of seeds that do _not_ fail on first attempt seem
> to reliably succeed on all subsequent attempts
> ** Suggesting that the root cause is something deterministic in the
> {{{}random(){}}}-ness of the test, and not something dependent on timing or
> concurrency.
