How to control position of Rollbar middleware in Rails stack

[v-kolesnikov]

How I can pге Rollbar middleware to the exactly position in Rails application stack?

If using rack or sinatra, it can be added manually, and the standard middleware methods like config.middleware.insert_after will work.

For rails, there currently isn't a config flag to prevent the gem from automatically inserting the middleware. I think it makes sense to add one.
