* Account for replication placement settings when balancing EC shards within racks.
* Update help contents for `ec.balance`.
* Add a few more representative test cases for `pickEcNodeToBalanceShardsInto()`.
* Improve EC shards rebalancing logic across nodes.
- Favor target nodes with less preexisting shards, to ensure a fair distribution.
- Randomize selection when multiple possible target nodes are available.
- Add logic to account for replication settings when selecting target nodes (currently disabled).
* Fix minor test typo.
* Clarify internal error messages for `pickEcNodeToBalanceShardsInto()`.
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).
* Rename `command_ec_encode_test.go` to `command_ec_common_test.go`.
All tests defined in this file are now for `command_ec_common.go`.
* Minor code cleanups.
- Fix broken `ec.balance` test.
- Rework integer ceiling division to not use floats, which can introduce precision errors.
* Introduce logic to resolve volume replica placement within EC rebalancing.
This will be used to make rebalancing logic topology-aware.
* Give shell.EcNode.dc a dedicated DataCenterId type.
* Refactor `ec.balance` logic into a `weeed/shell/command_ec_common.go` standalone function.
This is a prerequisite to unify the balance logic for `ec.balance` and `ec.encode'.
