Generalize the get_state return value in components

[francocipollone]

Summary

Nowadays the Component::get_state method is a bit flexible. No return type nor structure is demanded.

maliput_sim/maliput_sim/core/components.py

Lines 67 to 71 in 5809847

	def get_state(self):
	"""
	Get the current state of the component.
	"""
	pass

For example:

Name:

maliput_sim/maliput_sim/core/components.py

Lines 159 to 160 in 5809847

	def get_state(self) -> str:
	return self._name

Type:

maliput_sim/maliput_sim/core/components.py

Lines 173 to 174 in 5809847

	def get_state(self) -> str:
	return self._type

Pose:

maliput_sim/maliput_sim/core/components.py

Lines 194 to 195 in 5809847

	def get_state(self) -> list:
	return self._position + self._rotation

Velocity:

maliput_sim/maliput_sim/core/components.py

Lines 219 to 220 in 5809847

	def get_state(self):
	return self._linear + self._angular

Proposal

Expect a return type of Dict[str, Any].

Where the dictionary will compose by keys and values from the component:

• For Name: {'name' : 'A name'}
• For Type: {'type' : 'A type'}
• For Pose: {'position', [x, y ,z], 'rotation', [x, y ,z, w]}
• For Velocity: {'linear', [x, y ,z], 'angular', [x, y ,z]}

I think it is OK.
