Let's start labeling our CHANGELOG entries

Added the type attribute to a CHANGELOG entry. When you create a new
entry the software asks for the category of the change and sets the
associated type in the file.

The `merge_request` value is a reference to a merge request that adds this
entry, and the `author` key is used to give attribution to community
contributors. **Both are optional**.
The `type` field maps the category of the change,
valid options are: added, fixed, changed, deprecated, removed, security, other. **Type field is mandatory**.
Community contributors and core team members are encouraged to add their name to
the `author` field. GitLab team members **should not**.

$ bin/changelog 'Hey DZ, I added a feature to GitLab!'
```
At this point the script would ask you to select the category of the change (mapped to the `type` field in the entry):
```text
>> Please specify the category of your change:
1. New feature
2. Bug fix
3. Feature change
4. New deprecation
5. Feature removal
6. Security fix
7. Other
```
The entry filename is based on the name of the current Git branch. If you run
the command above on a branch called `feature/hey-dz`, it will generate a
`changelogs/unreleased/feature-hey-dz.yml` file.

`changelogs/unreleased-ee/` instead.
