v0.13.179

Changes

scheduler: ensure single lifo instance per route (#1945)
Multiple lifo filter instances on the route share the same job queue but claim multiple slots per request.
This is not obvious when users configure lifo filter in the ingress manifest and another instance is added
by the -default-filters-prepend flag.
The change keeps only the last lifo filter instance on the route to enable default configuration override.
