v2.2.0

Add symlink support

tsrc sync and tsrc init can now create symlinks as specified in the manifest file:

repos:

  - url: git@gitlab.local:proj1/app
    dest: app
    symlink:
      - source: app/some_file
        target: ../some_file

In this case, a symlink will be created from <workspace>/app/some_file to <workspace>/some_file.
(both source and target keys are relative to the repository's destination).

Changes related to groups

• log, status, and sync all learned about the --group option and the --all-cloned options
• foreach: remove the --groups-from-config options since this is now the default behavior

Misc

• Rework FAQ
• Run black in lint.sh
• Fix formatting of some messages
• Update code manifesto to suggest using docstrings in tests
