The cluster_template and cluster panels give the ability to define and launch a hadoop cluster (made from nodegroup_templates). They are in the same commit because some of the functionality of cluster_templates requires that the cluster panel also exist. This code was originally from: https://github.com/openstack/sahara-dashboard Change-Id: I85534b0dd97ce5def5f3a447d68c6aa206964f0a Partial-Implements: blueprint merge-sahara-dashboard Co-Authored-By: Nikita Konovalov <nkonovalov@mirantis.com> Co-Authored-By: Dmitry Mescheryakov <dmescheryakov@mirantis.com>
