Cellular Network Infrastructure

While investigating why some ttcn3-foo-test-latest jobs are failing (#3767), I have discovered that many Docker containers in docker-playground.git have additional Docker command-line arguments specified in their Makefile.

This is unexpected, because most Makefiles in that repository only have this line:

include ../make/Makefile

For osmo-msc-master it looks like this:

RUN_ARGS?=--rm --network sigtran --ip 172.18.0.10 -v msc-vol:/data

include ../make/Makefile

It is easy to overlook this, because the expected place for docker run arguments is the jenkins.sh file, e.g. ttcn3-msc-test/jenkins.sh:

...
echo Starting container with MSC
docker run    --rm \
        --network $NET_NAME --ip 172.18.1.10 \
        -v $VOL_BASE_DIR/msc:/data \
        -v $VOL_BASE_DIR/unix:/data/unix \
        --name ${BUILD_TAG}-msc -d \
        $REPO_USER/osmo-msc-$IMAGE_SUFFIX \
        osmo-msc
...

I have seen an error related to not being able to connect to 172.18.*0*.10 (the IP from the Makefile), so I'm assuming that the RUN_ARGS override what we specify in jenkins.sh. Need to look into this more though.
