Ship a few additional Sensu Handlers/Plugins

[portertech]

I think it would be great to put a few additional Sensu handlers & plugins in place.

Perhaps one or more of the following:

https://github.com/sensu/sensu-community-plugins/blob/master/handlers/metrics/graphite-tcp.rb
https://github.com/sensu/sensu-community-plugins/blob/master/plugins/redis/redis-graphite.rb
https://github.com/sensu/sensu-community-plugins/blob/master/plugins/network/check-banner.rb

Or clone the community plugins repo for all the things.
