Pre Deploy:

>>> from constance import config
>>> print(config.nautobot_golden_config__DEFAULT_FRAMEWORK)
{'all': 'netmiko'}
>>> print(config.nautobot_golden_config__GET_CONFIG_FRAMEWORK)

Post Deploy:

>>> from constance import config
>>> print(config.nautobot_golden_config__GET_CONFIG_FRAMEWORK)
{'cisco_nxos': 'netmiko', 'all': 'napalm'}
>>> print(config.nautobot_golden_config__DEFAULT_FRAMEWORK)
