Inifite loop in ai_translate entity reference with content

I created a MR that will avoid infinite loop.
The MR add a parameter "Maximum Reference Depth" that allow the user to limit the reference depth.
Default value is set to 1 so it translate only the first referenced element.

Remaining task :
It seem that even if the depth is larger than 1, the system extract correctly all the data but only translate the first level entity.
If the referenced entity reference an other entity again, the second entity will not be translated correctly.
This still need to be fixed.

Seems to work as expected for me :)

Thank you arwillame and thank you Paul for code review. Getting merged.
