Closes 20817 fix datasource sync broken when cron is set

[ifoughal]

Fixes: #20817

Datasources sync was broken when the user sets a sync interval.

The fix introduces 2 new states:

• Ready
• Scheduled

Ready state is set when the data-source object is not new. ie: either updated or changed state recently.
Scheduled is set when the user sets a sync interval.

This PR includes the following logic enhancements:

• by removing DataSourceStatusChoices.QUEUED from the ready_for_sync method, we let the user sync the data-source anytime even when a daily interval is set, as long as the data-source is enabled.

• Include the 2 new states (Scheduled, Ready) in the clean & save properties of data-source form model, to set the status correctly depending on the user inputs/

  • If the user creates a new data-source object, then the state is new.
  • if the user update the object with a defined interval, then the states changes to scheduled
  • if the user removed the sync interval, then the state changes to Ready.
  • if a sync is completed either successfully or with a failure, then the status will get update with the job's status as before without impact.

@ifoughal, CI appears to be failing with a test failure.

Initially I thought there was an issue with the view rendering class, but after some further TS, and checking the actual value of status on the DB entry, it seems the status field got overwritten somehow.

 id |            created            |         last_updated         | custom_field_data | description | comments | name | type |                           source_url                            | status | enabled | ignore_rules |                   parameters                   | last_synced | sync_interval

To circumvent this, I run the instance.save() method in the save override of dataSourcesForm. but this generates 2 commits and breaks the test. I'll continue looking into a fix.

The issue was coming from :

@classmethod
    def enqueue(cls, *args, **kwargs):
        job = super().enqueue(*args, **kwargs)

        # Update the DataSource's synchronization status to queued
        if datasource := job.object:
            datasource.status = DataSourceStatusChoices.QUEUED
            DataSource.objects.filter(pk=datasource.pk).update(status=datasource.status)

        return job

The enqueue method was overriding the state, I have removed datasource.status = DataSourceStatusChoices.QUEUED, the state should then be updated on the clean() method of the post of the datasource form.
