Updated patch attached.
* list of dirs/files was moved to class (the same way is in ipa-backup)
* log errors if dir/file cannot be removed (errors other than dir/file
does not exist)

Subject: [PATCH] IPA Restore: allows to specify files that should be removed
Some files/directories should be removed before backup files are copied
to filesystem.
In case of DNSSEC, the /var/lib/ipa/dnssec/tokens directory has to be
removed, otherwise tokens that are backed up and existing tokens will be
mixed and SOFTHSM log in will not work
