Show progress information when doing mass deployments

[thekorn]

when doing a mass deployment using e.g. "nodes_with_role" or a list of nodes I'd like to see some progress information in the output.

Right now it's like:

[...]
SUCCESS: Node correctly configured

== Configuring xxx.example.com ==
[...]

Something like:

[...]
SUCCESS: Node correctly configured

== Configuring xxx.example.com [2/32] ==
[...]

would be really helpful
