-------------------------------------------
Summary: Fix dead/dropped CDC lifecycle metrics and duplicate
SidecarCdcStats interface
Key: CASSSIDECAR-489
URL: https://issues.apache.org/jira/browse/CASSSIDECAR-489
Project: Sidecar for Apache Cassandra
Issue Type: Bug
Reporter: Jyothsna Konisa
Several SidecarCdcStats metrics in the CDC pipeline are declared and correctly
wired to the metrics backend but never actually invoked, so they've never had a
recorded value in production. Root cause traced to two issues: (1) a duplicate
SidecarCdcStats interface accidentally left over from open-sourcing, causing a
persister to be built with a no-op stub instead of the real stats instance, and
(2) several lifecycle/timing hooks with no call site at all. Also adds a new
metric for the configured CDC raw-directory space limit, which had no metric
coverage before.
