HDDS-14807. [Docs] Erasure Coding related metrics.
Please describe your PR in detail:
- Add the metrics related to Erasure Coding. to Core Concepts -> Replication
-> Erasure Coding
- Generated by the following three prompts using Gemini Cli + Gemini 2.5
Flash at Ozone's main repository:
```
> Find any metrics that is related to erasure coding. All metrics are
defined in files that end with Metrics.java, for example,
@hadoop-hdds/container-service/src/main/java/org/apache/hadoop/ozone/container/ec/reconstruction/ECReconstructionMetrics.java
To determine if a metric is related to erasure coding, find the variable
name, the description that has "ec" or "erasurecoding"
> Add to the bottom of @hadoop-hdds/docs/content/feature/ErasureCoding.md
These metrics span across Datanode, SCM and client. Useful for
troubleshooting EC problems. For each metric, create a table and include metric
name
in JMX, in Prometheus, and a description of the metric. Categorize them
based on the service roles: Datanode, SCM or client.
> @hadoop-hdds/docs/content/feature/ErasureCoding.md the Prometheus metric
names need correction.
For example:
scm_replication_manager_metrics_inflight_ec_replication -->
replication_manager_metrics_inflight_ec_replication
That is, remove the "scm_" prefix.
Similarly,
datanode_ec_reconstruction_metrics_block_group_reconstruction_total -->
ec_reconstruction_metrics_block_group_reconstruction_total
Remove the "datanode_" prefix.
Finally, client_xceiver_client_metrics_ec_reconstruction_total -->
xceiver_client_metrics_ec_reconstruction_total. Remove the "client_" prefix.
```
