https://github.com/cilium/cilium/pull/32313 introduced cluster name info at the Hubble flow Endpoint level. This PR adds corresponding filters on the Hubble server side, and two new --from-cluster and --to-cluster Hubble CLI flags leveraging the new filter.
For simplicity's sake the filter is a strict match for now, with the possibility to extend if/when the need arise (e.g. to RE2).
