Customize docker registry for ryuk image when using default resource reaper

[harrhp]

Is your feature request related to a problem? Please describe.
When default session of resource reaper is started it uses image that points to public registry, it is a problem when running tests in CI without internet access.

Describe the solution you'd like
Expose property in TestcontainersSettings that allows to specify registry (and tag ?) for ryuk image

Describe alternatives you've considered
It's probably possible to disable default resource reaper and manage session manually but it's more code

Additional context

OC, let's add this. What about IDockerImage TestcontainersSettings.ResourceReaperImage? We could achieve the same thing with HubImageNamePrefix, but the Ryuk image we're using right now is not on Docker Hub.

IDockerImage TestcontainersSettings.ResourceReaperImage is good, it would allow to change image name also (potentialy for another existing image or custom built image)
