Lisandro Pin 5725d2c464 Fix reporting of EC shard sizes from nodes to masters. 
SeaweedFS tracks EC shard sizes on topology data stuctures, but this information is never
relayed to master servers :( The end result is that commands reporting disk usage, such
as `volume.list` and `cluster.status`, yield incorrect figures when EC shards are present.

As an example for a simple 5-node test cluster, before...

```

Lisandro Pin 187ef65e8f Humanize output for weed.server by default (#7758) 
* 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.

Lisandro Pin ca499de1cb Improve EC shards rebalancing logic across racks (#6270) 
Improve EC shards rebalancing logic across racks.

  - Favor target shards with less preexisting shards, to ensure a fair distribution.
  - Randomize selection when multiple possible target shards are available.
  - Add logic to account for replication settings when selecting target shards (currently disabled).
