Specify a flavor_name (in form of a reg expression) to use.

Currently support http, https and ftp protocols
using the wget utility.

Using this option one can specify a file containing
ssh authentication keys to be uploaded and installed
on the newly created server.

Use stdout for info/debug messages and stderr for
warning/error messages.

User doesn't need to specify the UUID of the owner of
system images (it's usually hard to find it).

Instead save the uuids for these users for our production and
testing deployments inside a list (DEFAULT_SYSTEM_IMAGES_UUID) and
use that (uuids never change). If you need to specify another user
it's preferable to specify the image_id using the corresponding option.

Run 'devflow-update-version' to create all the version files, before
trying to build the docs.

Guess the branch to build, based on the current branch of the
repository. Also track all remote branches when cloning Synnefo, because
it is needed by devflow.

Add '--fetch-packages' option to snf-ci script, in order to download the
created debian packages.

Add 'config_file' argument to SynnefoCI in order to use a different
configuration file. Also, added the corresponding option to 'snf-ci'
scirpt.

Make 'ssh_keys' and 'accept_ssh_from' optional, since there are not
mandatory for ci to work.

Remove the 'deploy_on_io' option. Instead check if you will need to
compute manually the ssh port by the domain of the cyclades url.

Add option to use a custom image_id and flavor_id instead of getting
them from config file.

Get credentials for deployment from .kamakirc instead of config file.
Also, add option in config file indicating which cloud for kamaki to
use. Finally, add option in SynnefoCI to override the cloud from config.
