Monit doesn't stop sidekiq 6.0

[betesh]

This is a follow-up to #215. After resolving the issue there, I ran into later issues with monit failing to stop sidekiq.

The next at

opsworks_ruby/libraries/drivers_worker_sidekiq.rb

Line 52 in 1e9e32b

next unless File.file?(pid_file) && pid_exists?(File.open(pid_file).read)

is always executed because sidekiq 6 does not create a pid file.

Expected Behavior

Monit should stop sidekiq

Actual Behavior

Monit does not stop sidekiq
