We add the remove_non_local_host_ids() helper, which will be used in the next commit to support the read path. HostIdVector concept is introduced to be able to handle both host_id_vector_replica_set and host_id_vector_topology_change uniformly. The storage_proxy_coordinator_mutate_options class is declared outside of storage_proxy to avoid C++ compiler complaints about default field initializers. In particular, some storage_proxy methods use this class for optional parameters with default values, which is not allowed when the class is defined inside storage_proxy.
