What does this PR do?
It passes the docker_host key to the reaper creation when using the ReuseOrCreate container function, so that the reaper is able to extract the Docker host.
Reuse is available as a field in the GenericContainerRequest struct.
At the same time, the PR is adding tests to demonstrate the new behavior
Why is it important?
Consistency. Any other call to NewReaper is passing the host from the provider. Before these changes it was not passed, so the reaper directly returns
/var/run/docker.sock
when theTESTCONTAINERS_DOCKER_SOCKET_OVERRIDE
environment variable is not set.
