Move 'Running command...' from info to debug message

The follow output has been moved to a debug message now, since its more
for developers to debug:

[INFO    ] Running command under pid 24591: 'ssh
-oStrictHostKeyChecking=no -oUserKnownHostsFile=/dev/null
-oControlPath=none -oPasswordAuthentication=no
-oChallengeResponseAuthentication=no -oPubkeyAuthentication=yes
-oKbdInteractiveAuthentication=no -i /home/pabelanger/.ssh/id_rsa.pub
ubuntu@172.16.100.2 date'
