stop_wait_time config equivalent in kamal 2

[morgoth]

In kamal 1 we used stop_wait_time configuration option to enlarge time of closing the docker process during deploy, wich translated to docker stop -t #{stop_wait_time}.
This is well described in #678 (comment)

I don't see this configuration equivalent in kamal 2.
I think the proxy setting drain_timeout is not the same as it only affects containers with web requests and we need it for non-web roles.

Any advice how to migrate with this feature to kamal 2?
