Check have packages for extra features been installed before restoring backup 

`iparestore --full` should check that packages for extra features such as dns and adtrust
are installed in the system before restoring a backup in case the backup includes content
for these features. If the packages are not installed full backup should be refused and an
error message with suggestions should be showed.

If corresponding packages for these features are not installed before the backup
restoring, it may cause a situation when the packages are going to be installed after the
restoring. In that case configuration files restored by `ipa-restore` will be replaced by
default configuration files if the files are tracked by `rpm`. E.g. if
`freeipa-server-trust-ad` is not installed before `ipa-restore --full` running, when the
package will be installed it also will bring `samba` package according to the
dependencies. At `samba` installation step exist correct `/etc/samba/smb.conf` is going to
be replaced by the default one from the `samba` package.
