This PR enables the GetEnvoyBootstrapParams endpoint to construct envoy bootstrap parameters from v2 catalog and mesh resources.
* Make bootstrap request and response parameters less specific to services so that we can re-use them for workloads or service instances.
* Remove ServiceKind from bootstrap params response. This value was unused previously and is not needed for V2.
* Make access logs generation generic so that we can generate them using v1 or v2 resources.
