Remove berkshelf

Berkshelf is a dependency manager for Chef cookbooks. With it, you can depend on community cookbooks and include them in your workflow. Berkshelf is not useful when all cookbooks are local. ParallelCluster cookbook has all third party cookbooks ready locally.

Reducing software we depend on improves stability of the product. (e.g we have one known issue related to berkshelf https://github.com/aws/aws-parallelcluster/wiki/(3.8.0-%E2%80%90-3.9.3)-ParallelCluster-Build-Image-Failing-during-Installation-of-Minitar-Ruby-Gem-Dependency)
