      Description

      We can enable/disable tag compression along with WAL compression using the config,
      hbase.regionserver.wal.tags.enablecompression -> Defaults to true so that compress tags when WAL compress is ON.

      We are not storing this info abt whether a WAL containing compressed tags or not in the WAL header and use that in the read path. So dynamic change of this in some servers may cause issue when an RS having this value as true have to read and split a WAL generated from n RS where this value was false.
