Create default templates for Sahara

https://blueprints.launchpad.net/fuel/+spec/sahara-create-default-templates

Automatically creating plugins templates for Sahara

Problem description

A detailed description of the problem:

• Currently after succesful deployment of OpenStack with Sahara, templates for Sahara should be created manually. However, in order to determine if an environment is properly configured, Sahara plugins are necessary. That is why this spec adds the possibility to create Sahara plugin templates.

Proposed change

Automatic creation of Sahara plugins templates can be implemented by adding a Sahara post-install script, which will add templates for the following Sahara plugins:

• Vanilla;
• HortonWorks Data Platform (HDP);
• Cloudera distribution Hadoop (CDH);
