Fixed expected output from Crossbar check since it changed in KAZOO-707
Changed check_disk treshold from 85%-95% diskspace to 80%-90% to give us a bit more time to react
Changed the bigcouch_process check to be more specific
Replaced older Memory check with https://github.com/sensu/sensu-community-plugins/blob/master/plugins/system/check-ram.rb
Merge pull request #33 from x974/sensu

Fixed a bunch of checks, more to come!
