bq. I think we should add that anyway even though it doesn't help fix these
failures.
Let's open a separate issue for that. Internal HttpClient usage should be
getting an instance setup with the Retry policy that we want. I'm a little
skeptical that we just want to hard code it as off in the HttpSolrClient
constructor, but perhaps there is something to dig into there.
This upgrade is a bit scary at the moment. I see in one of the repeatable
connection reset issues, hard coding the Locale to English for the test makes
it pass. Other issues don't seem to relate to the Locale. Unless we can get to
the bottom of this quickly, we may want to pull this back and get a handle a
better handle on the problems before putting it in.

> Upgrade Jetty from 9.2 to 9.3

> Jetty 9.3 offers support for HTTP/2. Interest in HTTP/2 or its predecessor
> SPDY was shown in [SOLR-6699|https://issues.apache.org/jira/browse/SOLR-6699]
> and [on the mailing list|http://markmail.org/message/jyhcmwexn65gbdsx].
> Among the HTTP/2 benefits over HTTP/1.1 relevant to Solr are:
> * multiplexing requests over a single TCP connection ("streams")
> * canceling a single request without closing the TCP connection
> * removing [head-of-line
> blocking|https://http2.github.io/faq/#why-is-http2-multiplexed]
> * header compression
> Caveats:
> * Jetty 9.3 is at M2, not released.
> * Full Solr support for HTTP/2 would require more work than just upgrading
> Jetty. The server configuration would need to change and a new HTTP client
> ([Jetty's own
> client|https://github.com/eclipse/jetty.project/tree/master/jetty-http2],
> [Square's OkHttp|http://square.github.io/okhttp/],
> [etc.|https://github.com/http2/http2-spec/wiki/Implementations]) would need
> to be selected and wired up. Perhaps this is worthy of a branch?
