##### SUMMARY
`docker_container` should so some sanity checks that not two volumes / mount points use the same target inside the container, so that especially when recreating containers, they won't be destroyed first before recreating fails.

This becomes more important once #49808 is merged.

##### ISSUE TYPE
- Bug Report

##### COMPONENT NAME

##### ANSIBLE VERSION
