> A common ask from our customers is for an easy way to enable replication for all tables within a namespace, but we had noticed that setting *NAMESPACES* option when adding a peer has no effect on enabling replication for the defined namespaces tables, it still replicates only entries where the *CF REPLICATION_SCOPE* is set to '1'.
> The problem is due to the chaining of *ScopeWALEntryFilter* and *NamespaceTableCfWALEntryFilter* together. This is currently done on *BaseReplicationEndpoint* class, but these two filters are not compatible, as *ScopeWALEntryFilter.filterCells* logic filters out cells from CFs where REPLICATION_SCOPE property is set to 0, before *NamespaceTableCfWALEntryFilter.filterCells* can have a chance to apply it's own logic, based on namespace definition.
> This PR changes the logic described above, making  *ScopeWALEntryFilter* and *NamespaceTableCfWALEntryFilter* mutual exclusive, allowing for entries from all tables within the defined namespaces to be replicated without needing to have *REPLICATION_SCOPE* set to true.
