Update list of Delayed Job plugins

[jturkel]

The extensibility in Delayed Job is a great, enabling developers to add all kinds of cool functionality. The only problem is it can be really hard to find Delayed Job plugins to do what you're looking for. The ecosystem wiki page is a start but it doesn't have much on it and it's not linked from the README making it hard to find. Resque does a great job maintaining a list of plugins which really encourages a community plugin development and use.

Please consider updating the ecosystem wiki page (and linking to it from the README) with the following candidates I found trolling through Github (only some of which I've used). I'm also happy to go ahead and make the edit myself if you're ok with it:

• d4be4st / progress_job
  Progress reporting for Delayed job
• amitree / delayed_job_recurring
  Extends delayed_job to support recurring jobs
• salsify / delayed_job_groups_plugin
  Job groups for delayed_job
• salsify / delayed_job_worker_pool
  Worker process pooling for Delayed Job
• sportngin / delayed_job_loner
  Gem that adds the ability to prevent duplicate delayed jobs from being created.
• d4be4st / mina-delayed_job
  Mina plugin to manage delayed_jobs
• joeyAghion / opsworks_delayed_job
  Chef cookbook for configuring an AWS OpsWorks layer of delayed_job workers.
• capistrano-plugins / capistrano-delayed-job
  Capistrano tasks for automatic and sensible DelayedJob configuration
• benjaminoakes / delayed-plugins-airbrake
  delayed_job exception notification with airbrake
• kumichou / delayed_job_sqs
  Amazon SQS backend for delayed_job
• supportify / delayed_job_azure

Gem is designed to "Split or Break" Time Taking Jobs(Delayed Jobs, Crons, Bulk Operations, etc.) into smaller size Mutually Exclusive Delayed Jobs. These Sub-Jobs can be picked by "Multiple Workers" in "Single" or "Multiple Servers". After splitting and enqueuing, the process will wait for the sub-jobs to complete and also processes sub-jobs instead of blocking.
"Parallelism" can be achieved across multiple servers through Delayed Jobs which can directly impact performance. "Performance" can improve up to "n+1" times, where n = number of workers picking the jobs.

Gem: dj_split - nehalamin93/dj_split

Parallelise Time Taking Job across Multiple Processes in Single or Multiple Servers by Splitting into Delayed Jobs.

Please consider the addition of this Delayed Job plugin in the ecosystem wiki page (and linking to it from the README).
