Drist release with persistent ssh

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.
