refactor notes to remove requirement to edit code on new model

[jon-nfc]

Currently when adding a new tenancy model, you must edit the notes code for that model to be able to add notes.

Details

refactor the notes so that the model name is used instead of hard coded logic to add a note to a model.

Current code

centurion_erp/app/core/models/notes.py

Lines 81 to 119 in ed0e57c

	config_group = models.ForeignKey(
	ConfigGroups,
	on_delete=models.CASCADE,
	default = None,
	null = True,
	blank= True
	)
	device = models.ForeignKey(
	Device,
	on_delete=models.CASCADE,
	default = None,
	null = True,
	blank= True
	)
	service = models.ForeignKey(
	Service,
	on_delete=models.CASCADE,
	default = None,
	null = True,
	blank= True
	)
	software = models.ForeignKey(
	Software,
	on_delete=models.CASCADE,
	default = None,
	null = True,
	blank= True
	)
	operatingsystem = models.ForeignKey(
	OperatingSystem,
	on_delete=models.CASCADE,
	default = None,
	null = True,
	blank= True
	)

This logic must be adjusted to use an item_id? and a model. Where item_id is the models PK the note is for and model is the model name.
