Version 0.4.0 - 7/12/2015

[poliva83]

1. Added http_port to one_image resource so that port other than 8066 (default) can be used to upload images.
2. Replaced :credentials and :secret_file driver options with profiles.
3. Fixed ssh timeout; :timeout will be applied to each ssh command and overall timeout to establish a ssh session is 5 min.
4. one_image now takes 'download_url' as an optional attribute; 'image_file' still takes precedence over 'download_url'. If 'download_url' is specified then that location is used for image and it will not try to start HTTP server locally.
5. Changed default port for HTTP server in one_image to be 8066 instead of previously used port 80.
6. Added :mode attribute to one_image, one_template and one_vnet resources.
7. Added bootstrap_options[:mode] so that machines can be created with different permissions.
