Fix ClusterLoadAssignment timeouts dropping endpoints. (#19871) When a large number of upstreams are configured on a single envoy proxy, there was a chance that it would timeout when waiting for ClusterLoadAssignments. While this doesn't always immediately cause issues, consul-dataplane instances appear to consistently drop endpoints from their configurations after an xDS connection is re-established (the server dies, random disconnect, etc). This commit adds an `xds_fetch_timeout_ms` config to service registrations so that users can set the value higher for large instances that have many upstreams. The timeout can be disabled by setting a value of `0`. This configuration was introduced to reduce the risk of causing a breaking change for users if there is ever a scenario where endpoints would never be received. Rather than just always blocking indefinitely or for a significantly longer period of time, this config will affect only the service instance associated with it.
