test cases should not change the global random states

[wyli]

the current NumpyImageTestCase2D and NumpyImageTestCase3D use create_test_image_*

MONAI/tests/utils.py

Line 444 in 866d53d

im, msk = create_test_image_2d(self.im_shape[0], self.im_shape[1], 4, 20, 0, self.num_classes)

without the local random_state parameter

MONAI/monai/data/synthetic.py

Line 29 in 866d53d

random_state: Optional[np.random.RandomState] = None,

the relevant unit tests therefore become dependent on each other via the global random state. this should be rectified

Hi @madil90 ,

Could you please help enhance the create_test_image_2d() and create_test_image_3d() functions as @wyli suggested?
You can refer to this: https://github.com/Project-MONAI/MONAI/blob/master/tests/test_rand_lambdad.py#L20.

Thanks in advance.
