Change a random function to the new gym, and delete prng function.

@zhaolongkzz why has this PR not been merged yet? I encountered the same problem. Are there any other changes that need to be made?

[zhaolongkzz]

@veds12 you can install gym==0.10.5 or modify code like: in code multiagent-particle-envs/multiagent/multi_discrete.py

import gym
# from gym.spaces import prng             # prng has been canceled

# and change:
random_array = np.random.RandomState().rand(self.num_discrete_space)

[veds12]

Ya I figured that out from one of the issues. But why not merge this?

[zhaolongkzz]

@veds12 maybe nobody updates this repository
