Clean up usage of lusis/chef-kibana cookbook

* Set kibana cookbook to specific revision to avoid insanity
    * See the Changelog for v1.2.0 of lusis/chef-kibana:
      https://github.com/lusis/chef-kibana/commit/f09e26a4c6c531c15e7a5bca232cd4bb48fe860d#diff-2
    * Ensure we use chef-kibana ~> 1.2.0 so we can do file-based installs
        * Ths is a forward-thinking version constraint; as 1.2.0 hasn't
        been tagged or released yet
* Update nginx config to match latest from kibana cookbook
    * Maintains basic auth changes we've made
* Switch to file-based install for Kibana; we don't need full source
    * Just grabs the released build of Kibana, instead of cloning the
    whole repo
Bump to v1.3.2
