Simple knife helper to fully kill nodes (including their corresponding client data) from the chef server. It provides two commands for this:

$ knife killer execute NODE_NAME1 NODE_NAME2

This is used for removing instances explicitly. However, you may just want to remove them with a search:

$ knife killer slaughter "roles:fubar"

Or perhaps you just want to kill things that haven't checked in for more than 60 minutes:

$ knife killer slaughter -M 60

Which you can combine with the searching:

$ knife killer slaughter -M 60 "roles:fubar"

Pretty simple plugin just to make common process faster.
