docs(examples): containerize supply-chain-app

Uses a Docker-in-Docker container to run the supply chain app example which itself has functionality that spawns docker containers to host the AIO ledger images. This makes it a 100% turn-key way of providing examples to anyone who have at least the ability to run docker containers built for the linux amd64 platform. Fixes #486 Signed-off-by: Peter Somogyvari <peter.somogyvari@accenture.com>

-git clone https://github.com/hyperledger/cactus.git
-cd cactus
-npm install
-npm run configure
-cd examples/supply-chain-app/
-npm install --no-package-lock

+1. Run the following command to pull up the container that will run the example application and the test ledgers as well:
+    ```sh
+    docker run \
+      --rm \
+      --privileged \
+      -p 3000:3000 \
+      -p 3100:3100 \
+      -p 4000:4000 \
+      -p 4100:4100 \
+      hyperledger/cactus-example-supply-chain-app:2021-02-03-be1bc02
+    ```
+2. Wait for the output to show the message `INFO (api-server): Cactus Cockpit reachable http://0.0.0.0:3100`
+3. Visit http://localhost:3100 in a web browser with Javascript enabled
+4. Use the graphical user interface to create data on both ledgers and observe that a consistent view of the data from different ledgers is provided.
 
 Once the last command has finished executing, open link printed on the console with a web browser of your choice
