Expected Behavior

ShardID in write_cache metrics should be actual.

Current Behavior

Wrong shardID in write_cache metrics

Steps to Reproduce (for bugs)

  1. Load objects to system
  2. Get shards list
root@acidrock-node3:~# sudo frostfs-cli --endpoint 127.0.0.1:8091 -w /etc/frostfs/storage/wallet.json --config /tmp/storage.yaml control shards list |grep Shard

Suggest to add path of the write_cache to metric labels. It will be more informative.
As example

# HELP frostfs_node_fstree_mode FSTree mode value
# TYPE frostfs_node_fstree_mode gauge

If easier, lets add path in a separate task, it is not a bug.
