.Synopsis
   Initialize a restic environment for the main script     
.DESCRIPTION
   By using this script, the main script will have an environment ready for backup.
   It will load, from the $BackupConfigPath folder received as parameter of the main script:
    - common.ps1
    - common_windows.ps1 or common_unix.ps1, depending on the running platform
    - $BackupConfigName like config_template.ps1, received as parameter of the main script
