What does this PR do? What is the motivation?
Documents CSI driver-based injection as the default SSI injection mode on Kubernetes (previously init containers), in preparation for the default change going live.
Changes:
single-step-apm/kubernetes.md: Markscsias the default mode andinit_containeras the alternative; removes the Preview label. Completes the Helm and Operator config examples so they enable the CSI driver (datadog.csi.enabled/global.csi.enabled) alongsideinjectionMode: csi. Addsautoto the per-pod annotation values. Adds a GKE Autopilot caveat.tracing/guide/injectors.md: Adds the CSI mechanism explanation (per-node DaemonSet, download-once-and-cache) to the Kubernetes section as the conceptual home. Flips the default-delivery statement to CSI, and fixes two spots that assumed init-container mode.Internal-only material from the source doc (competitive positioning, customer case study) was intentionally excluded.
injectionMode: The source material specifies 1.28.0, but the existing docs said 1.25.0. I used 1.28.0 in this PR (two locations inkubernetes.md). Please confirm the correct minimum.csiinjection mode is not compatible with GKE Autopilot. Note thatcontainers/kubernetes/csi_driver.mddocuments the CSI driver as supported on GKE Autopilot. I've documented this as: the driver can be installed on Autopilot, butcsiinjection mode is not supported there (useinit_container). Please confirm this distinction is accurate.Merge instructions
Merge readiness:
Note: This should merge in step with the CSI-as-default change going live.
