Dan Prince 04bfd491ad Add mechanism to send error messages to helper. ... Adds a new err_msg function which is used to: -echo feedback to the deploy ramdisk console -keep track of the first error message we hit so that we can send it along to the baremetal-deploy-helper. Also, updates our wget request back to baremetal-deploy-helper to include the first the first error message (if any) as the 'e' parameter. The err_msg uses a new simple safe_url_encode function to ensure we don't send invalid characters in our HTTP post requests.
