Added basic Chef Solo support
Added basic support for Chef Solo, allowing users to bootstrap nodes with Chef without having a Chef Server. In order to bootstrap the nodes, a tarball with the cookbooks must be made available to the node. This can be done by uploading the file to the node using the jclous ssh client, or by providing a public URL where the tarball can be downloaded from. The tarball *must* have a root folder called *cookbooks* and all cookbooks must be inside it. Once the tarball is available, the ChefSolo statement can be used to generate the bootstrap script.
