Disconnect logic to fill in role parents

[AlanCoding]

SUMMARY

For code removals after RBAC changes, this is my first pass, since it is the most mechanistic change.

A role (in the old system) has both parent roles and ancestor roles tracked in relationships. We have already disconnected the logic for rebuilding ancestors but rebuilding parents is more minimal... although still maintained via connected signals.

The goal of this PR is to gut the signals for role parent rebuilding. This gets weird in a few cases, like how editing related ForeignKey fields can change role parents. I want to also be thorough about tracing de-referenced methods and deleting them.

The checks here are actually looking fairly okay-ish to me. Just need to get some integration testing results to confirm that nothing unexpected is happening.

Question: should we also remove the role parents/children sub-endpoint with this change?

awx/awx/api/views/__init__.py

Lines 4464 to 4489 in 7ed0eee

	class RoleParentsList(SubListAPIView):
	deprecated = True
	model = models.Role
	serializer_class = serializers.RoleSerializer
	parent_model = models.Role
	relationship = 'parents'
	permission_classes = (IsAuthenticated,)
	search_fields = ('role_field', 'content_type__model')
	def get_queryset(self):
	role = models.Role.objects.get(pk=self.kwargs['pk'])
	return models.Role.filter_visible_roles(self.request.user, role.parents.all())
	class RoleChildrenList(SubListAPIView):
	deprecated = True
	model = models.Role
	serializer_class = serializers.RoleSerializer
	parent_model = models.Role
	relationship = 'children'
	permission_classes = (IsAuthenticated,)
	search_fields = ('role_field', 'content_type__model')
	def get_queryset(self):
	role = models.Role.objects.get(pk=self.kwargs['pk'])
	return models.Role.filter_visible_roles(self.request.user, role.children.all())

They won't be correct after this (I'd expect they'll have nothing.
