[MANOPD-86838] Resolve conflict of archive names in add_node and restore procedures

[ilia1243]

Description

• restore after add_node fails with "[Errno 13] Permission denied"
• The reason is in '/tmp/kubemarine-backup.tar.gz' archive that is left after add_node procedure, belongs to root, and prevents uploading of different archive with the same name during restore.

Solution

• Use archives with different names for different purposes.
