Synnefo

ci: Allow the use of local repo

Instead of cloning Synnefo from its official repo,
user can choose (using --local-repo option, or by not
setting the synnefo_repo config parameter) to use
his local repo.

ci: Install x2goserver

ci: Automatic yes to apt-get prompts

ci: Fix bugs with path expansion

Python does not do any automatic path expansions.
User has to call functions such as expanduser() and
expandvars().

Add uesr's id_rsa.pub file as default ssh_keys file.

ci: Implement file lock mechanism for temp_config

Before writing to temp config file, acquire a lock
and re-read it's contents to make sure we don't
overwrite anything.

ci: Add --force-yes option to apt-get install

ci: Include user images and config improvements

Include the user images in the list of images that are matched against
the image name from the config file. Also, change config file to use
archipelago flavors and create instances from the SynnefoCI image.

ci: Get flavor by name

The option flavor_name support a list of flavors to try.

Refs #4192

ci: Temporary_config supports multiple machines

Use one temporary_config that will contain information
about every machine we have build until now, so we
can go back and use/inspect one of them.

Refs #4199

ci: Make some options optional

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

ci: Merge 'fetch_packages.py' to snf-ci script

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

ci: Parse branch from repository

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.

ci: Add option to build and fetch documentation

ci: s/mail/email in git config

ci: turn system_uuid option into a hardcoded one

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...

ci: Add --ssh-keys command line option

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

ci: Specify a flavor_name instead of a flavor_id

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

ci: Fix some typos in utils.py

ci: Fixes to ci code

• override config file from env variable
• pep8 fixes
• do not display vm password
• fail if cloning repo fails
• do not use eval

ci: Get credentials by kamakirc

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.

Refs #4193

ci: Remove 'deploy_on_io' option

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.
