This feature was here mainly for testing and is quite different from the
other method.

In order to simplify and then, optimize the process, we decide to remove
this feature.

You can still create your own deploy script using surge and the
nexylan/ci configuration variables.

BREAKING CHANGE: Surge deploy support is not provided anymore.

BREAKING CHANGE: Deploy job names was changed and simplified. Simply use
deploy without the deploy mode suffix. See related doc diff for details.

BREAKING CHANGE: if you use only/except keyword on nexylan/ci job
overrides, you will have to replace them by the new rules keyword.

fix: gitlab 13.0 compatibility

Closes #42
