Update Readme to include Puppet’s open source Bolt
Bolt is akin to PDQ Deploy in the sense that you can run scripts against multiple client types to help configure nodes in an environment. Except that bolt is agentless too!
* [GNU Make](http://www.gnu.org/software/make/) - The most popular automation build tool for many purposes.
* [Gradle](http://gradle.org/) - Another build automation system.
* [Rake](https://github.com/ruby/rake) - Build automation tool similar to Make, written in and extensible in Ruby.
+* [Bolt](https://puppet.com/products/bolt) - You can use Bolt to run one-off tasks, scripts to automate the provisioning and management of some nodes, you can use Bolt to move a step beyond scripts, and make them shareable.
