Freeze release workflow (#242)

* Freeze release workflow

- Do not pull anything from master

- Do not push release commit to master

- Only push created version tag

* Refine scripts to start new version

1. Cherry-pick hotfixes from released version

2. Bump version to new version

Normally, 1 is only made of the release commit updating CHANGELOG
with the release date.

However, if a release branch was needed to apply hotfixes to the
latest release, cherry picking will account for the whole release
branch (i.e. multiple commits).

* Ignore more paths for unit testing
