Epic CRDB-33829

Release note(security, ops): Cluster settings for host based authentication configuration (`server.host_based_authentication.configuration`) and identity map configuration(`server.identity_map.configuration`) need to be redacted as they can  be configured to contain LDAP bind usernames, passwords and mapping of external identities to sql users which are sensitive and should be configurable for redaction via `server.redact_sensitive_settings.enabled` cluster setting.
