* Update plugins/delete-project from branch 'master'
  to 0322a37009071da525bfd8569e98538c2e8891d5
  - Provide less verbose repo delete method
    
    Currently, the repo delete method exposed is too verbose, and forces
    the client to provide parameters for preserving and archiving the repo.
    
    Provide a less verbose method with sensible defaults.
    Annotate the method so its clear it will be used by the pull-
    replication plugin, this will also prevent accidental removal of the
    method impacting the pull-replication plugin.
