DQN for flow

[pengyuan-zhou]

Hi,

This is a branch to enable DQN (also by ray) for flow.
Currently it supports single agent and multi-agent tests on traffic_light_grid scripts.

Other examples can be easily enabled by modifying corresponding example file, env file and test file, according to the modifications in this branch.

Cheers,
Pengyuan

Ya I have zero ideas why the build fails, it works on my pc (without the unittest).

Putting aside the build failure, this sets RLlibs DQN as the default option. We'd prefer you make it so that there's a choice of algorithm, of which DQN is one. You can look at train.py in the flow_maddpg branch for an example.

Sure, I'll revise it. BTW in that train.py, is the TD3 in setup_exps_rllib same with the one in h-baseline?

This looks good to me minus comments! @pengyuan-zhou if the changes are made I will merge.

Hey! I'm really sorry about the state of things here, we are working on getting a new maintainer in the next week or so so this doesn't happen again.
