CLI: Long list of containers is 1+N

[justinsb]

Doing a long list of containers (swift list --long) produces slow output. It does a HEAD query per bucket.

It should instead just do a JSON list of buckets and output the results without a query-per-bucket.

Seems like it :

(two cont called foo and bar on this testvm)

stack@devstack:~$ swift --debug list --long 2>&1 |grep curl|grep -v keystonecl

Yeah, that's pretty terrible. What if we just drop all of the `long` handling in service.py, and have shell.py always print '????-??-?? ??:??:??' for containers? Possibly with some --yes-really option to go back and do the actual HEADs.

Does anyone actually use or get value from the dates returned? It isn't even the Last-Modified for the container; it's the X-Timestamp (which is more like ctime than mtime). What if we just dropped the column entirely?
