New restore role

[t-woerner]

There is a new restore role in the roles folder:

roles/iparestore

This role allows to restore an IPA server locally and from the controller
and also to copy a backup from the controller to the server.

Here is the documentation for the role:

roles/ipabackup/README.md

New example playbooks have been added:

playbooks/restore-server.yml
playbooks/restore-server-from-controller.yml
playbooks/copy-backup-to-server.yml

The vars are copied form the ipaserver role to be able to install the
needed packages. The vars should be moved into a common role to be consumed
by ipaserver, ipareplica and iparestore roles later on.

Except for a minor documentation issue, looks good.

I have added support for the NTP service in the firewall for IPA 4.6.

There is a new PR with a combined backup and restore role: #430
