Add a create-hooks command for import Rake task

With the introduction of hashed storage, the import Rake task needs to be able
to copy a repo and then initialize the hooks as a separate step from creating
the project directory.

Relates to gitlab-org/gitlab-ce#41739 and
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/16280
