6afa0a463d unsupported: expose collisionMargin to changeDynamics/getDynamicsInfo.
add cube_convex.urdf for testing this collisionMargin. Test script:
import pybullet as p
import time
p.connect(p.GUI)
plane = p.loadURDF("plane_implicit.urdf")
cube = p.loadURDF("cube_convex.urdf",[0,0,1])
p.setGravity(0,0,-10)
while (1):
	p.stepSimulation()
	pts = p.getContactPoints()
	p.changeDynamics(plane,-1,collisionMargin=0.3)
	p.changeDynamics(cube,-1,collisionMargin=0.3)
	print("===================")
	print("cube pos=", p.getBasePositionAndOrientation(cube)[0])
	print("margin=", p.getDynamicsInfo(plane,-1)[11])
	#time.sleep(1./10.)
