house cleaning
refactor Cucumber::Chef::Config rename [:provider] to .provider
added chef and test_lab config settings
use new chef and test lab config settings
default provider should now be vagrant
channel the proper stdout, err and in to ZTK::SSH; add a bootstrap_ssh helper
implement ssh with bootstrap credentials option
removed the bootstrap class
raise an exception instead
typo fix
refactored the provisioner; bootstrap now renders the script locally; then uploads and executes the file instead of embedding the file via "/bin/bash -c" command; this allows for more useful debugging via set -v/-x
