admin: Refactor task destination planning (#7063)

* refactor planning into task detection

* refactoring worker tasks

* refactor

* compiles, but only balance task is registered

* compiles, but has nil exception

* avoid nil logger

* add back ec task

* setting ec log directory

* implement balance and vacuum tasks

* EC tasks will no longer fail with "file not found" errors

* Use ReceiveFile API to send locally generated shards

* distributing shard files and ecx,ecj,vif files

* generate .ecx files correctly

* do not mount all possible EC shards (0-13) on every destination

* use constants

* delete all replicas

* rename files

* pass in volume size to tasks
