I think we should cover capacity decreases like you suggest as well as we are still in the middle of mutating the infrastructure. |

This seems like the behaviour I'd expect. Probably |
It's a bit confusing to have Terraform poll until instances come up on ASG creation but not on update. This changes update to also poll if min_size or desired_capacity are changed. This changes the waiting behavior to wait for precisely the desired number of instances instead of that number as a "minimum". I believe this shouldn't have any undue side effects, and the behavior can still be opted out of by setting `wait_for_capacity_timeout` to 0.

…waiting It was a mistake to switched fully to `==` when activating waiting for capacity on updates in #3947. Users that didn't set `min_elb_capacity == desired_capacity` and instead treated it as an actual "minimum" would see timeouts for every create, since their target numbers would never be reached exactly. Here, we fix that regression by restoring the minimum waiting behavior during creates. In order to preserve all the stated behavior, I had to split out different criteria for create and update, criteria which are now exhaustively unit tested. The set of fields that affect capacity waiting behavior has become a bit of a mess. Next major release I'd like to rework all of these into a more consistently named block of config. For now, just getting the behavior correct and documented. Fixes #4792
