OCPBUGS-113338: align to upstream - 11-09 - #301

The commented relabeling examples for the pod and service monitors used
target_label. ServiceMonitor and PodMonitor relabelings are Prometheus
Operator RelabelConfigs, which are camelCase, so copying the example
produces an object the API server rejects the field of:
Warning: unknown field "spec.endpoints[0].relabelings[0].target_label"
The neighbouring sourceLabels in the same examples, and the targetLabel
used further down in this file, are already camelCase.

Replace the IPv6 regex used to extract nexthop addresses from `ip route` output. Regex alternation is order-sensitive and still truncates valid compressed forms such as 2001:db8:1:2::5:6 and 2001:db8::8a2e:370:7334. Parse the first token after "via" with net.ParseIP instead, which handles all standard IPv6 notations including zone identifiers and IPv4-mapped addresses. Add unit tests covering the reported cases.

Docker Hub jnorwood helm-docs v1.14.2 immutable digest
💡 Result:
The Docker image jnorwood/helm-docs:v1.14.2 is associated with the immutable image digest sha256:7e562b49ab6b1dbc50c3da8f2dd6ffa8a5c6bba327b1c6335cc15ce29267979c [1][2]. In the Docker ecosystem, a tag (like v1.14.2) is mutable and can be updated to point to different image builds over time [3]. Conversely, an image digest is a unique, cryptographic identifier (SHA-256 hash) that represents the specific, immutable content of an image [3]. By referencing the image using this digest rather than the tag, users ensure they are pulling the exact same content regardless of any future changes to the v1.14.2 tag [3]. For the v1.14.2 release, the jnorwood/helm-docs project transitioned to using digests for its GitHub Actions, reflecting a commitment to ensuring build reproducibility and security [4]. Users and projects often pin to this specific digest to avoid potential discrepancies or security risks associated with mutable tags [1][2][5].

Validate every matching counter.
ForPod can return metrics from both metricshttps and frrmetricshttps ports. ValidateGaugeValueCompare checks every matching scrape, but ValidateCounterValue accepts only the first match through CounterValue. A later matching counter can fail check while validation succeeds. Iterate over all matching counters in ValidateCounterValue; keep CounterValue for callers that intentionally select one raw value.

Hold the read lock through advertisement merge and send.
mergedAdvertisementsPerIP() returns an interface snapshot before gratuitous() reacquires RLock. SetBalancer() can replace that snapshot while ipRefcnt remains positive for another advertisement. Because gratuitous() rechecks only ipRefcnt, it can send an ARP or NDP announcement through an interface that the current advertisement no longer selects. Keep the merge and send in one RLock scope, and use an internal send helper that does not acquire the lock again.
