When performing a resize, we'll want to (by default) select target hosts from the source cell to do a traditional resize if possible before considering target hosts in another cell which will be slower and more complicated. If the source cell is disabled or target flavor is not available in the source cell, then we'll have no choice but to select a host from another cell. But all things being equal between hosts, we want to stay within the source cell (by default). Therefore this change adds a new CrossCellWeigher and related configuration option to prefer hosts within the source cell when moving a server. The weigher is completely noop unless a cross-cell move is permitted by configuration, which will be provided in a future change.
