New feature: Plugins installation

[egarbi]

This formula is great, I would like to have also, let's say a plugin.sls state to install every input/output plugin listed on pillars.
something like (for an output plugin):

logstash-output-{{logstash.outputs.plugin_name}}:
  gem.installed:
    - ruby: jruby@jgemset

Since plugins are now available as gem:

./gem search logstash-output-s3

*** REMOTE GEMS ***

logstash-output-s3 (0.1.6)

What do you think?

Over a year later: yes, that would be nice. Maybe I'll implement that as well.
