A custom remediation that is not a string raises an exception on config plan generation

[jeffkala]

Environment

• Python version:
• Nautobot version:
• nautobot-golden-config version:

Expected Behavior

If a feature is using custom remediation that results in structured data, the generated config plan should check if the feature is custom and just reply with that data instead of trying to split on the string.

Observed Behavior

Custom remediations purpose is to allow for remediations to provide non-CLI based data. The below line intimates we only allow strings in remediation "field".

nautobot-app-golden-config/nautobot_golden_config/jobs.py

Line 446 in 16f9a3c

config_set="\n".join(config_sets),

Steps to Reproduce

1. Do the pre-reqs to get GC app up and running.
2. Setup a custom remediation in PLUGIN_CONFIG and have the custom remediation return structured data.
3. Generate a config plan "type remediation" on that custom remediation feature.

A potential option is to check isinstance...could also instead try to chec kif custom_remediation bool is true

            if not isinstance(config_sets, str):
                config_set = config_sets
            else:
                config_set="\n".join(config_sets)
            config_plan = ConfigPlan.objects.create(
                device=device,
                plan_type=self._plan_type,
                config_set=config_set,
                change_control_id=self._change_control_id,
                change_control_url=self._change_control_url,
                status=self.plan_status,
                plan_result=self.job_result,
            )
    ```
