Migrate post_userDelete hook to share manager

This makes the post_userDelete hook call the sharemanager. This will
cleanup to and from this user.

* All shares owned by this user
* All shares with this user (user)
* All custom group shares
* All link share initiated by this user (to avoid invisible link shares)

Unit tests are added for the defaultshare provider as well as the
federated share provider
