Backport
This PR is auto-generated from #16352 to be assessed for backporting due to the inclusion of the label backport/1.4.x.
The below text is copied from the body of the original PR.
This PR adds tracking of pause containers to the docker driver, fixing a bug introduced by #15898 where the containers are now subject to dangling container reconciliation. The pause container created for allocs with docker tasks making use of bridge networking is not created in the same flow as a normal Task - which have a
TaskHandlestate. The set of tasks not to reconcile was identified by scanning the set of these states, which does not include pause containers.To remedy this, this PR now tracks pause containers in their own little store. Since the Nomad Client may be restarted, we scan existing running containers on startup to reload the store from existing running containers.
Fixes: #16338
