ZOOKEEPER-3765: Use https everywhere possible

* Redirect http://zookeeper.apache.org to https://zookeeper.apache.org
* Update any links to use https where possible
* Remove search-hadoop.com search box because
  1. It won't work on secure browsers (because it uses http for form
     submission) or, at the very least, it will show a mixed-content
     security warning when accessing https://zookeeper.apache.org
  2. More importantly, the site doesn't work to show legitimate search
     results... the domain appears to have been taken over by an
     advertising service.
* Also update copyright date in NOTICE, while I was in there
