Make repeating `-r` work
For now Gitlab::Triage::Options#require
is a single value, therefore repeating -r
will overwrite it. Make it an array, and require all of them in the engine so we can repeat -r
just like we're using it for the Ruby options.
Not only Ruby options, a lot of Ruby tools like unicorn, rib, and so on does the same thing that repeating -r
just works.
