EnvoyFilter match.routeConfiguration.vhost.name semantics change

EnvoyFilter matches rely on internal implementation details to match generated xDS segments, which is subject to change at any time.

In this release, the virtual host name match may have different results.

Previously, each domain name had its own virtual host. As an optimization, multiple domains may use a single virtual host. This means that an Envoy Filter previously matching a specific virtual host may now apply to more domains than in previous releases.

This optimization may be temporarily disabled by setting PILOT_ENABLE_ROUTE_COLLAPSE_OPTIMIZATION=false on the Istiod deployment.
