specify delayed_job queue

Hi!
This is for my question in #563.

This will certainly break the existing behaviour where people assume jobs are run on the default delayed_job queue. It should be possible to add this feature, but doing it this way won't work.

[rokob]

One approach would be to add an option similar to https://github.com/rollbar/rollbar-gem/blob/master/lib/rollbar/configuration.rb#L163 in the configuration for delayed_job here https://github.com/rollbar/rollbar-gem/blob/master/lib/rollbar/configuration.rb#L148, and then if a queue is set on the delayed job class you can use that in the call method otherwise use the current default way of doing it.

I've changed my bits according to your advice. Is it ok now?

Looks good to me, thanks!
