Does this mean that local is a reserved cell name and no one can use it for their cells? We need to document that.

if err != nil {
return nil, fmt.Errorf("could not fetch cell info: %v", err)
}
if len(cells) == 0 {
return nil, fmt.Errorf("no local cells have been created yet")
}
cell = cells[0]
} else {
cell = *localCell
}
cell = *localCell
}

// If a keyspace is provided then return the specified srvkeyspace.
