Clean up a custom Docker network on DLE failure
Goal
DLE creates its own Docker network. On a retrieval error, the Docker network continues to exist.
If there are too many networks on the machine, an error occurs:
[ERROR] Error response from daemon: could not find an available,
non-overlapping IPv4 address pool among the defaults to assign to the networkTODO / How to implement
On DLE retrieval failure:
- disconnect containers from a custom Docker network
- clean up custom Docker networks
