6b98b52acc Fix reporting of EC shard sizes from nodes to masters. (#7835) 
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...

```

79fa87bad4 Rework parameters passing for functions within ec.rebuild (#7445) 
* Rework parameters passing for functions within `ec.rebuild`

This simplifies the overall codebase and allows to cleanly handle parallelization via waitgroups.

* fix copy source

* add tests

* remove tests not useful

* fmt

* nil check
