cml_node module does not use params x, y and tags

[tvarohohlavy]

cml_node module has following params defined, but they are not used.

ansible-cml/plugins/modules/cml_node.py

Lines 70 to 84 in 716c622

	x:
	description: X coordinate on topology canvas
	required: false
	type: int
	y:
	description: Y coordinate on topology canvas
	required: false
	type: int
	tags:
	description: List of tags
	required: false
	type: list
	elements: str

The bahvior should be probably for coordinates:

• absent: does not matter
• present:
  a) if specified: make sure the node has them so update of coordinates can happen
  b) if not specified: does not matter (or we could add it next to right/left most existing node)
• started: does not matter
• stopped: does not matter
• wiped: does not matter

The bahvior should be probably for tags:

• absent: does not matter
• present:
  a) if specified: make sure the node has them so update of tags can happen
  b) if not specified: does not matter
  c) if specified as empty list: delete existing tags
• started: does not matter
• stopped: does not matter
• wiped: does not matter

Any suggestions?
