DEX-16897: Mitigate envoy proxy out of memory issue

In a cluster with many services, the envoy proxy side may encounter out of memory issue due to the large number of services it has to keep track of. By using Sidecar CRD, the envoy proxy sidecar explicitly tracks only the namespaces or services that it is interested in, therefore reduces the number of services it has to track, and chances of having the out of memory issue. This issue is fixed.
