[keoo]

Only tested it in my home, need more tests. To be reviewed for the next release, no rush needed

[rchakode]

The PR contains commits already integrated in vishnu. Could you rebase it?

Update for -h in CLI

[keoo]

Update based on Rodrigue advices :

• vishnu_ping pings everybody by default
• vishnu_ping filters by machine and name (not given -> everybody pinged)

NB : dispatcher has no machine filter, so filtering by machine only does not ping him

Fix when nothing inscribed in dispatcher

[keoo]

Removed allPing service, all is done by the ping now

Automatically register sed does not work with SSL
