Merging docker ignore file from the backup service into the one in the root directory of the project.

Hard to come up with a certain plan here.
Services have to build, as usual, this is a build change.
To better check this, you'd have to manually log into the shell of a certain service and list files to see if the files listed in docker ignore are not copied to the container. You can add ls -l command to the CMD command in Dockerfiles
