There are sets of common steps that we very often want to "bookend" all of our deployments with. One concrete example would be: sending out a Manual Intervention to confirm when all servers are confirmed live before stamping a new deployment in NewRelic.

Right now, everyone has to bake these steps into their own projects by adding the Manual Intervention step followed by the NewRelic Deployment Stamp step. If it were possible to create what I would call "Composite Step Templates" then I could define a reusable step template that was made up of other step templates. That way, instead of everyone having to repeat all of the possible steps in their own projects, they would simply include this one composite step and they'd be done.

Now, my composite example was only two steps to keep it simple, but you can imagine maybe a composite is made up of more than that. Or even imagine a change in policy where the Manual Intervention email has to include more information. Everyone has to repeat this stuff in all their projects and having the ability to put it into a composite step would alleviate all of that.

Sometimes you need to run a script notify other systems before or after a deployment, such as monitoring systems load-balancers etc. (currently we ping NewRelic when we deploy).

To do this in the current powershell script model you have to be creative by somehow running the script on one of the tentacles. Though there are several ways of doing this they all lead to annoying management issues since you essentially have to choose a tantacle to run the script on. One issue could be that if the tentacle is decommissioned the script stops running (without warning). It would be nice if it were simpler to do this.

So I'm basically asking you to make it easier to run a script once before and/or after the deployment, without having to figure out where to run the script. Maybe it could be run on the octopus server, or maybe octopus could automatically choose an arbitrary tentacle to run the script.
