The token-list used by the connectors changed the location to conf/lists. The user needs to copy and paste the files to get started with the gateway.
This PR solves that issue by copying the files when doing the setup

Tests performed by the developer:

• Run gateway-setup.sh and check that the files are there.
• Build the docker image and start the container and check that the files where there too.

     • @cardosofede by setting up docker build, we have to use gateway-create.sh instead and the current works as expected if Y on the prompt to copy default token list file. I opened a ticket about this few days ago if this helps Docker - Unhandled error in background tasks due to no such file or directory  #145.
   • Tried to setup a docker compose file below using the docker image built using this PR, no avail
     
     • Tried with adding conf/list on the compose file and still the same result
