Deprecated clean{ start | stop | restart} commands

To reduce confusion among Euca admins, removed non-standard
init-script commands for the CC. Old commands are still accessible
for backward compatibility. Changes are as follows:

  start -> faststart
  stop -> faststop
  restart -> fastrestart
  cleanstart -> start | cleanstart
  cleanstop -> stop | cleanstop
  cleanrestart -> restart | cleanrestart

Fixes EUCA-5129
