[openstack-dev] [oslo][osdk] PrettyTable needs a home in OpenStack

And here is a simple converter that uses tabulate but has somewhat like 
the pretty table object format that people are used to (could be away to 
get 90% of the common usage over to tabulate, minus the special 
prettytable users that are doing advanced things).


The grid output/format of tabulate seems to be pretty close to what 
prettytable output/format is (but my guess is there is some variation, 
just because of different authors/codebases...)
