Allow "Instructions" on manual intervention step to contain variables
The instruction field on a manual intervention is currently limited to just hard coded text. It would be helpful if it could display variables from a deployment. This would allow me to:
1) Run a script which:
1a) gets the current deployed version
1b) gets the new version being deployed
1c) contacts our build tool (Teamcity in my case) to get information on the changes involved in the build
1d) create a list of hyperlinks to each change between the two versions.
2) Contact our ticketing system to get the details of the release
3)Display those links to the code changes and the requested release in the instructions so a deployer can look over the changes and make sure it aligns. E.g. The release is supposed to be to fix something in a payment module but the code changes show that there was also a change checked into the email notification module.
This would allow us to do an easy last minute sanity check before going forward with a deployment.
