Fixes

• CPU profile of Gloo at scale (5000+ upstreams) indicated that the generateXDSSnapshot function was taking upwards of 5 seconds of CPU on a ~50 second sample. This change optimizes the code by using creating hashes for the XDS snapshot using deterministic proto marshalling and fnv hashing rather than the reflection-based mitchellh/hashstructure which was benchmarked to be several orders of magnitude slower. (#4084)
• CPU profile of Gloo at scale (5000+ upstreams) indicated that the endpointsForUpstream function was taking upwards of 5 seconds of CPU on a ~50 second sample. This change optimizes the code by using a map instead of looping over all endpoints for each upstream. (#4084)
• Gloo Edge now proactively reports warnings on virtual services that have matchers that are short-circuited.
  To enable, update the Gloo Settings such that spec.gateway.validation.warnRouteShortCircuiting=true
  The cases now additionally covered are:
  • routes that have simple OR regex header matchers, ensuring each one of the OR'ed matchers can be reached
  • the same logic, but with method matchers
    In addition, we support aggressively reporting errors on virtual services with invalid regex matchers. (no need
    to enable short-circuiting reporting) (#3334)
• Fix a race condition in the gateway-validation-webhook, where resources applied concurrently can avoid validation. (#4136)
