lttng add-trigger: replace log level options with --log-level

Implement the proposal to replace the --loglevel and --loglevel-only
options with a single --log-level option.

The syntax of the argument to --log-level is:

 - `LEVEL`: to specify only this level
 - `LEVEL..`: to specify from this level up to the most critical level
 - `..`: to specify any level. Basically the same as no `--log-level`
         option.

The intent is to keep the door open to fully support ranges with the
`LEVEL1..LEVEL2` syntax.  The loglevel_parse_range_string function and
friends are implement this, but their caller in add_trigger.c,
parse_log_level_string, artificially restricts it to the two cases
shown above.
