Owner add command cannot add maintainers as documented

[eproxus]

The documentation states:

$ rebar3 help hex owner
...
Supported command combinations:
 ...
 rebar3 hex owner add <package> <username> <level>
...

But running rebar3 hex owner add foo bar maintainer add the user as an owner instead. Using rebar3 hex owner add foo bar --level maintainer works, as documented further down in the man page.

What is a maintainer btw? It's not documented anywhere on Hex or in Mix/Rebar...

Fully agree 💯 ...

This should be documented in hex.pm and perhaps in rebar3_hex as well.

One distinction is a "full" owner can transfer a package, where as a maintainer can only publish, retire, etc. iirc. Would ask @ericmj to correct me if I'm wrong.

The levels have a more use in organizations also iirc.
