> As described in IEP-47 defragmentation is performed when a node enters a special mode called maintenance mode.
> Discussion on dev-list clarifies algorithm to enter maintenance mode:
>  # Special key is written to local metastorage.
>  # Node is restarted.
>  # Node observes the key on startup and enters maintenance mode.
> Node should be fully-functioning in that mode but should not join the rest of the cluster and participate in any regular activity like handling cache operations.
