Dustin Specker c234b72abd tools: generalize execute_shipyard_action
This enables passing any combination of actions and parameters to this
script.  This also makes it easier to add scripts for additional actions
by not having to modify execute_shipyard_action.

Updated redeploy_server to pass in servers as a param.
