Adds a new annotation vault.hashicorp.com/agent-native-sidecar to inject Vault Agent as a native sidecar. Adds a startupProbe that looks for /home/vault/.native-sidecar-started, which relies on https://github.com/hashicorp/vault/pull/27582 to place that file once all the templates have been rendered at least once.
