Provide a non-static way to provide read/connect timeouts

[nddipiazza]

You put the connect and read timeouts in

BoxGlobalSettings java class in static ints

  private static int connectTimeout = 0;
  private static int readTimeout = 0;

Now in a multi-tenant application everyone's settings mess with each others. This setting doesn't belong in a static location.

@nddipiazza I opened a PR to add methods to BoxAPIConnection for setting per-connection timeouts; this should be included in the next SDK release.

Thank you!
