The option --log-level was not completely described in the usage text,

A new value "help" is accepted after --log-level to give more details
about the syntax and listing the log types and levels.

The array "levels" used for level name parsing is replaced with
a (modified) existing function which was used in rte_log_dump().

If we forget about the slightly different formatting, why not simply
reuse rte_log_dump?
It has the advantage of listing the default level for each logtype
that a user cannot guess otherwise.
