Fix tests for Apache HTTP Client 4.5 and greater

Must explicitly close the underlying HttpClient instance to ensure
pooled connections are closed between between tests.  Otherwise stale
connections exist from previous test and which fail on use with
NoHttpResponseException errors.

Bug 572026 - Support Jetty 9 and 10

Make USS-SDK work with Jetty 9 and 10.  Note that Jetty 10
made some bundle changes

- Pull in javax.servlet APIs through import-package
- Fix uses of sendError() to setStatus() to preserve response headers
- Remove deprecated Jetty logger; tests now show Jetty output,
  which is actually useful

- added new .target for eclipse-latest, orbit-latest, and jetty 10
  for use as an Eclipse target platform for development
- added new profiles to build and test for other named Eclipse releases

    mvn -Declipse.target=neon verify

  or use the following to test with Jetty 10

    mvn -Declipse.target=latest verify
