RenewableTlsUtils starting two non-daemon threads

[KiranMohan]

The RenewableTlsUtils starts two thread - reloadSslFactoryWhenFileStoreChanges and reloadSslFactory - both of which are not marked as daemon threads. This prevents on-demand java processes from from exiting. This is a bug IMHO and must be fixed by marking the threads as daemon or providing some mechanism to close the threads.

Good catch! Do you want to help contribute a fix?

Yes. I will raise merge request in a day or two.
