[MEDIUM] stats: add "show table [<name>]" to dump a stick-table

It is now possible to dump a table's contents with keys, expire,
use count, and various data using the command above on the stats
socket.

"show table" only shows main table stats, while "show table <name>"
dumps table contents, only if the socket level is admin.
