Feature request: Interactive manifest mode

[Ryan Finnie]

This is an idea Tom suggested after I encountered a situation where I would need to mitigate a (hopefully temporary) kernel bug. I could have written a script which applied the mitigation at the right point, but it would be unneeded (and unwanted) as a permanent fix. What I ended up doing was editing the manifest, commenting out everything after the point I needed, applying the mitigation to the affected nodes, reverting the comments and re-running the manifest.

A better option would be a command line flag to run the manifest interactively, pausing for confirmation before each action in the manifest. Something like:

About to run:
    deploy config=neutron-gateway.conf

[(Y)es] / (N)o / (S)top / (C)ontinue without interaction
Run this action? ([y]/n/s/c)
