JENA-1263: Recommended redirect behavior


> Configure HTTP client to follow 303 redirects

> When calling RDFDataMgr.read(Model model, String uri), the underlying HTTP 
> client does not appear to follow 303 redirects. For example:
> {code:java}
> Model m = createDefaultModel();
> RDFDataMgr.read(m, "http://purl.org/dc/terms/";);
> {code}
> {code}
> org.apache.jena.riot.RiotException: Failed to determine the content type: 
> (URI=http://purl.org/dc/terms/ : stream=text/html)
> {code}
> A work-around is to add a static block with a custom HTTP client like so:
> {code:java}
> static {
>     HttpOp.setDefaultHttpClient(
>             HttpClientBuilder.create().setRedirectStrategy(
>                     new LaxRedirectStrategy()).build());
> }
> {code}
> By default the Apache HTTP client follows 301 and 302 redirects (but not 303 
> redirects), but the W3C recommends using 303 redirects for publishing RDF 
> vocabularies (https://www.w3.org/TR/swbp-vocab-pub/), which is what the 
> Dublin Core vocabularies use.
> This sort of redirect handling worked previously, e.g. Jena 3.1.0; it would 
> be convenient if the underlying HTTP client simply followed the 303 redirects.
