Generate vp_list.txt on the collector automatically from ansible

Alternative deployments, besides having to provision the list of vantage points in the inventory in the “Local” directory, also need to adapt the vp_list.txt file on the collector with their list of vantage points manually. The vp_list.txt file could be generated from the inventory as well.

Would you consider a PR that would implement this?

Alternative deployments differ from RSSAC047. Please ask your sponsors before working on this. If they say that adding features that are not in RSSAC047 is part of your contract, and that we can have a "do this as RSSAC047" configuration setting that is on by default, adding those features is just fine.

Sorry for not being clear. I didn't mean an alternative deployment, but just a deployment of the initial implementation in this repository that completely follows RSSAC047v2 guidelines outlined in section 3 of RSSAC047v2.

Also my usage of the word "feature" was probably wrong. The proposal was to help eliminate the hardcoded constants that are part of the deployment configuration and not of the implementation. Other than the vp_list.txt no deployment configuration is hardcoded in the implementation. Besides that, the list of vantage points is also in your ansible inventory, right?

I think I see where you are going on this, and that sounds fine. Do it as a PR and I'll only object if it doesn't follow 047.
