       Description: 
       
       Drist see its release 1.04 available. This adds support for the flag
       `-p` to
       make the ssh connection persistent across the script using the ssh
       ControlMaster feature. This fixes one use case where you modify ssh
       keys in two
       operations: copy file + script to change permissions and this makes
       drist a lot
       faster for fast tasks.
       
       Drist makes a first ssh connection to get the real hostname of the
       remote
       machine, and then will ssh for each step (copy, copy-hostname, absent,
       absent-hostname, script, script-hostname), this mean in the use case
       where you
       copy one file and reload a service, it was doing **3** connections. Now
       with
       the persistent flag, drist will keep the first connection and reusing
       it,
       closing the control socket at the end of the script.
       
       Drist is now 121 lines long.
