ensemble ssh should passthrough args to ssh

[Mark Mims]

trying to do stuff like:

    for i in {1..10}
    do
        ensemble ssh nfs-client/$i 'cat /opt/storage/testfile'
    done

but can't pass args in to ssh

Agree 100% .. HOWEVER, ssh in a for loop is bad.. what we really need is an arbitrary hook capability.
