Clean up the image functional test

1. Move setup_docker.sh to tools directory

2. Make a setup_gate.sh that installs necessary packages including
   docker and starts docker.

3. Add logging output.

4. Add default test timeout of 2 hours.

5. Add user to the docker group before running test cases.

6. Run image build as dockerroot group.

This patch has to be one commit to fix the gate in one go.
