Provide ability to restore backed up domain during installation.
There are existing commands that allow a user to backup a domain (config +
deployed apps) as well as restore the domain. What about offering
an option in the installer to restore a domain from a backup zip?
The scenario would be something like this:
1) The user manually (backup-domain CLI) backed up the domain.
2) The system the DAS is on crashes so the user runs the installer on
another system to reinstall GF.
3) As part of that install process they are given the option to restore
the domain(s) from backups they may be maintaining.
4) We can also give them the option to ping existing instances to
update the DAS coordinates (if they happened to change based on
the move to new HW).
