* [Generator] Add DRAIN span_name sanitizer * Fix linter * Fix formatting * Update default manifest * Fix build error in update-fixtures * Remove bad test * Remove misleading comment * Add per-tenant override for drain mode * Do a machines job * Address PR feedback * Address PR review: rename drain_mode config and improve sanitizer - Rename `drain_mode` to `span_name_sanitization` across all config, legacy config, interfaces, and overrides for better user-facing clarity - Add explicit default value "disabled" in RegisterFlagsAndApplyDefaults - Add ValidateSpanNameSanitization function in validation/fields.go - Rename metrics to remove DRAIN reference: `drain_spans_compacted_total` -> `spans_sanitized_total` `post_drain_demand_estimate` -> `post_sanitization_demand_estimate` - Pass configured staleDuration to NewDrainSanitizer instead of hardcoded 15min, consistent with other registry components - Extract "span_name" magic string to labelSpanName constant - Update all tests with new names and signatures * Update manifest * Use empty string as disabled * Update CHANGELOG.md Co-authored-by: Suraj Nath <[email protected]> * Update manifest --------- Co-authored-by: Suraj Nath <[email protected]>
