- add judoscaler gem to allow judoscale use in heroku environments
- This will allow auto scaling for both web and worker dynos across both
standard-1x/2x and performance dynos
- This will scaling in response to queue time rather than response
time(heroku default)
- This also allows you to scale multiple dynos in and out at once,
rather than scaling them one at a time, as is the default.
