The following set of functions covering defragmentation happy-case needed:
 * Initialization of defragmentation manager when node is started in maintenance mode.
 * Information about partition files is gathered by defrag mgr.
 * For each partition file corresponding file of defragmented partition is created and initialized.
 * Keys are transferred from old partitions to new partitions.
