TYRUS-355: HTTP Redirect - Location header cannot be a relative address
 - normalized location header is now resolved against last requested URI so we always get absolute URI
TYRUS-358: ClientEndpointConfig.Configurator only gets the first HTTP header with the same name.
	Fixed for servlet, Grizzly server, Grizzly client, JDK client.
Test spit into a deployable and non-deployable test
