[ros2 topic pub][ros2 service call] Cannot populate nested arrays

[mikaelarguedas]

Bug report

Steps to reproduce issue

ros2 topic pub /chatter test_msgs/DynamicArrayNested "{primitive_values: [{string_value: 'foo', int8_value: 42}]}"

Expected behavior

Populate and send a DynamicArrayNested message with the following content:

test_msgs.msg.DynamicArrayNested(primitive_values=[test_msgs.msg.Primitives(bool_value=False, byte_value=b'\x00', char_value='\x00', float32_value=0.0, float64_value=0.0, int8_value=42, uint8_value=0, int16_value=0, uint16_value=0, int32_value=0, uint32_value=0, int64_value=0, uint64_value=0, string_value='foo')])

Actual behavior

$ ros2 topic pub /chatter test_msgs/DynamicArrayNested "{primitive_values: [{string_value: 'foo', int8_value: 1}]}"
Failed to populate field 'primitive_values': The 'primitive_values' field must be a set or sequence and each value of type 'Primitives'

Additional information

The tool has currently no way of knowing what type the fields of the array should be. See ros2/rosidl#243 for more information about the features required to get this working
