Resolves [Feature]: Grafana dashboards for metrics exporter #7811

Description of the changes

Added a new Grafana dashboard definition jaeger-v2.json in [monitoring/jaeger-mixin/dashboards.libsonnet] that uses OpenTelemetry Collector metrics (otelcol_*) instead of legacy Jaeger metrics.
Added a helper function qpsPanelSuccessError to [dashboards.libsonnet] to streamline panel creation.
Generated the corresponding dashboard JSON file: [monitoring/jaeger-mixin/dashboard-v2-for-grafana.json].
This provides visual observability for Jaeger v2 components (Collector, Exporters, Queue) using the new metric names (e.g., otelcol_receiver_accepted_spans, otelcol_exporter_queue_size).

How was this change tested?

Generated the dashboard using [jsonnet] and jb to ensure valid syntax and successful compilation.
Manually inspected the generated [dashboard-v2-for-grafana.json] file to verify that the PromQL queries correctly target the expected otelcol_ metrics and that the panel structure is correct.
Added [monitoring/jaeger-mixin/tests.jsonnet] to programmatically verify the dashboard title and panel count.

is monitoring/jaeger-mixin/README.md still accurate after these changes?

I've updated the README to remove the now-obsolete warning about V2 metric incompatibility. Since the default dashboard and alerts are now V2-native, the documentation is consistent with the code.

Makefile


 .PHONY: lint
-lint: lint-fmt lint-license lint-imports lint-semconv lint-goversion lint-goleak lint-go
+lint: lint-fmt lint-license lint-imports lint-semconv lint-goversion lint-goleak lint-go lint-monitoring


this is not something we change that often to include this in the main lint target. We can add a workflow that is only executed if files in this dir are changed.

scripts/lint/lint-monitoring.sh

+cd monitoring/jaeger-mixin
+
+# Install dependencies
+~/go/bin/jb install


there is no guarantee that this is where go installs binaries. You can use the approach we have in internal/tools, add a separate target to scripts/makefiles/Tools.mk
