Pads a tensor.
tf.raw_ops.PadV2(
    input, paddings, constant_values, name=None
)
This operation pads input according to the paddings and constant_values
you specify. paddings is an integer tensor with shape [Dn, 2], where n is
the rank of input. For each dimension D of input, paddings[D, 0] indicates
how many padding values to add before the contents of input in that dimension,
and paddings[D, 1] indicates how many padding values to add after the contents
of input in that dimension. constant_values is a scalar tensor of the same
type as input that indicates the value to use for padding input.
The padded size of each dimension D of the output is:
paddings(D, 0) + input.dim_size(D) + paddings(D, 1)
For example:
# 't' is [[1, 1], [2, 2]]
# 'paddings' is [[1, 1], [2, 2]]
# 'constant_values' is 0
# rank of 't' is 2
pad(t, paddings) ==> [[0, 0, 0, 0, 0, 0]
                      [0, 0, 1, 1, 0, 0]
                      [0, 0, 2, 2, 0, 0]
                      [0, 0, 0, 0, 0, 0]]
