> The 'list_regions' shell command gets a list of regions for a given table and
> then prints them and some attributes such as the server where they are
> located, current request count, data locality, and such.
> However if a region is in transition the command might fail with
> {{ERROR: undefined method `getDataLocality' for nil:NilClass}}
> and there may be other ways this can happen. Protect against use of nil
> references and just display what we can.
