Give `cluster.status` detailed file metrics for regular volumes (#7791) 

* Implement a `weed shell` command to return a status overview of the cluster.

Detailed file information will be implemented in a follow-up MR. Note also
that masters are currently not reporting back EC shard sizes correctly, via
`master_pb.VolumeEcShardInformationMessage.shard_sizes`.

F.ex:

```
> status

cluster:
	id:       topo
	status:   LOCKED
	nodes:    10
	topology: 1 DC(s)s, 1 disk(s) on 1 rack(s)

volumes:
	total:    3 volumes on 1 collections
	max size: 31457280000 bytes
	regular:  2/80 volumes on 6 replicas, 6 writable (100.00%), 0 read-only (0.00%)
	EC:       1 EC volumes on 14 shards (14.00 shards/volume)

storage:
	total:           186024424 bytes
	regular volumes: 186024424 bytes
	EC volumes:      0 bytes
	raw:             558073152 bytes on volume replicas, 0 bytes on EC shard files
```

* Humanize output for `weed.server` by default.

Makes things more readable :)

```
> cluster.status

cluster:
	id:       topo
	status:   LOCKED
	nodes:    10
	topology: 1 DC, 10 disks on 1 rack

volumes:
	total:    3 volumes, 1 collection
	max size: 32 GB
	regular:  2/80 volumes on 6 replicas, 6 writable (100%), 0 read-only (0%)
	EC:       1 EC volume on 14 shards (14 shards/volume)

storage:
	total:           172 MB
	regular volumes: 172 MB
	EC volumes:      0 B
	raw:             516 MB on volume replicas, 0 B on EC shards
```

```
> cluster.status --humanize=false

cluster:
	id:       topo
	status:   LOCKED
	nodes:    10
	topology: 1 DC(s), 10 disk(s) on 1 rack(s)

volumes:
	total:    3 volume(s), 1 collection(s)
	max size: 31457280000 byte(s)
	regular:  2/80 volume(s) on 6 replica(s), 5 writable (83.33%), 1 read-only (16.67%)
	EC:       1 EC volume(s) on 14 shard(s) (14.00 shards/volume)

storage:
	total:           172128072 byte(s)
	regular volumes: 172128072 byte(s)
	EC volumes:      0 byte(s)
	raw:             516384216 byte(s) on volume replicas, 0 byte(s) on EC shards
```

Also adds unit tests, and reshuffles test files handling for clarity.

* `cluster.status`: Add detailed file metrics for regular volumes.
