Use chef-solo for all core Crowbar barclamps. [8/10]

This pull request has the following changes:

* Add a chef-solo jig that uses chef-solo to make changes to nodes.
  The chef jig still exists, but it is not used or installed by
  default.
* Port all roles that used the chef jig to use chef-solo, making
  whatever minor fixups are needed along the way.
