Problem Description

The current implementation of container stop timeout covers all containers https://watchtower.nickfedor.com/v1.22.0/configuration/update-behavior/?h=timeout#container_stop_timeout

I'd like to be able to set a different stop timeout for certain containers as some need a longer grace period.

Desired Solution

A label com.centurylinklabs.watchtower.stop-timeout

Current Alternatives or Workarounds

Setting the global timeout to the longest container grace period
