Add box files for eucalyptus.2

splunk server runs on ec2linux (which is redhat-based).

Now the install happens in the current directory, with logs in a 'logs'
subdirectory.

downloaded, because the RELEASE value is invalid.  Curl also doesn't
print as large a progress bar.  The script fails early if there's no
RELEASE specified.
