The .git directory is used to identify the release number

WARNING! To pass the SECRET_KEY as en env variable, you should use
base64 encoding as the key is supposed to be a random string of bytes.

See https://docs.gitlab.com/ee/ci/yaml/README.html#artifacts-reports-junit

New variable required to generate ZTP configuration.

or dict).

Updating to 2.2.1 introduced some regressions.
Some fields (vars, hosts) are empty when editing an Ansible group.

Using the latest version probably require some code changes.

Using flask-login request_loader, we can validate jwt tokens.
This allows to use the same decorators for the web UI (using cookies)
and the API (using JWT) as well as the current_user local proxy.

New get_json method on test client response.
See http://flask.pocoo.org/docs/1.0/testing/#testing-json-apis

- requirements-to-freeze.txt is used to list only the needed packages
- requirements.txt is used to build a reproducible environment
- requirements-dev.txt is for testing and building the documentation

The official flask-bootstrap is still not compatible with bootstrap 4.
The application basically only uses the main template and one macro.
It's easier to include directly bootstrap in CSEntry.
It makes upgrading to the latest bootstrap much easier and removes a
dependency.

Update to bootstrap 4.1.3

Added:
- jquery-3.3.1.min.js
- bootstrap.bundle.min.js (include popper but not jquery)

Note that jquery.slim can't be used.
We need for example $.getJSON for datatables.

This is not super clean. The model and device_type belong to the host.
This is for easy access from the API.
But it would be better to have a "expand=true" query parameter and return the
host as a dict.

- add ansible_groups_hosts_table for many-to-many relationship between
groups and hosts
- add new api endpoint /network/groups

JIRA INFRA-412

Allow to enter Ansible variables on host in YAML format.
Use codemirror (http://codemirror.net) to make editing YAML easier.
