Unify the re-balancing logic for ec.encode with ec.balance. (#6339) 
Among others, this enables recent changes related to topology aware
re-balancing at EC encoding time.

Account for replication placement settings when balancing EC shards within the same rack. (#6317) 
* 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 (#6297) 
* 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()`.

Introduce logic to resolve volume replica placement within EC rebalancing. (#6254) 
* 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… (#6195) 
* 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'.

9f9ef1340c use streaming mode for long poll grpc calls 
streaming mode would create separate grpc connections for each call.
this is to ensure the long poll connections are properly closed.
