move towards user-data being binary

UrlResponse: biggest change... make readurl return bytes, making user
             know what to do with it.
util: add load_tfile_or_url for loading text file or url
      as  read_file_or_url now returns bytes

ec2_utils: all meta-data is text, remove non-obvious string translations
DigitalOcean: adjust for ec2_utils

DataSourceGCE, DataSourceMAAS: user-data is binary other fields are text.
openstack.py: read paths without decoding to text.  This is ok as paths
              other than user-data are json, and load_json will handle

load_file still returns text, and that is what most things use.
