Data augmentation

For example:

a=tf.constant([[[1],[2]],
               [[3],[4]]])
# rotating `a` counter clockwise by 90 degrees
a_rot=tf.image.rot90(a)
print(a_rot[...,0].numpy())
[[2 4]
 [1 3]]
# rotating `a` counter clockwise by 270 degrees
a_rot=tf.image.rot90(a, k=3)
print(a_rot[...,0].numpy())
[[3 1]
 [4 2]]

Args
`image`	4-D Tensor of shape `[batch, height, width, channels]` or 3-D Tensor of shape `[height, width, channels]`.
`k`	A scalar integer. The number of times the image is rotated by 90 degrees.
`name`	A name for this operation (optional).

Returns
A rotated tensor of the same type and shape as `image`.

Raises
`ValueError`	if the shape of `image` not supported.
