Add normalization strict incremental feature flag (#22514)

* maybe add feature flag? * pattern matching * also add version check * formatting * refactor test also * extract test + fix method call * minor tweaks * add context to log message * put workspace id in normalization input * use non-semver tag * add flag for version of normalization * also flag old version * add test * missed part of the commit * format * add test for null workspace ID * Revert "also flag old version" This reverts commit 3be601d. * Revert "missed part of the commit" This reverts commit 47a67b4. * always apply flag, even if we're behind a version * derp * Add more logging to the normalization activity * Update charts and kustomize for the feature flag * Format --------- Co-authored-by: Edward Gao <edward.gao@airbyte.io>
