Upgrade to Jetty 9.4.15.v20190215

In addition to upgrading to Jetty 9.4.15, this commit updates the
KeyStores used in embedded container testing to add to their entries
subject alternative name extensions for localhost and 127.0.0.1. As
of 9.4.16, Jetty requires the SAN extensions.

Closes gh-16188
