feat(projectHistoryLogs): record project history logs for imports TASK-944

[rgraber]

📣 Summary

Record every time a user replaces the form on a survey via an import

👀 Preview steps

1. ℹ️ Create a survey called MyProject
2. Go to Form -> ... -> Download XLS and save the file as 'MyProject.xls'
3. Download
   XLSForm_Settings.xlsx
4. Go to Form and click the 'Replace Form' icon
5. Select Upload an XLS form and upload MyProject.xls
6. Go to api/v2/audit-logs/?q=metadata__asset_uid:<asset uid> AND log_type='project-history'
7. 🟢 There should a log with the action replace-form (order doesn't matter) and the usual metadata plus latest_version_uid.
8. Click Replace Form again and upload XLSForm_Settings.xlsx. This should change the title of the project.
9. Reload the endpoint
10. 🟢 Reload the endpoint. There should be two new logs, one with action=update-name and the other with action=replace-form (order doesn't matter). The log metadata should have all the information as the previous one. The update-name log should additionally have

'name': {
   'old': <oldname>,
   'new': 'Sample Settings Form',
}

12. Upload MyProject.xls to Google Drive and open in Google Sheets
13. Go to File -> Share -> Publish to Web and publish as xlsx (entire document). Copy the link.
14. Back in KoboToolbox, replace the from again and select Import an XLS from via URL
15. Paste the Google Drive url and import
16. 🟢 Reload the endpoint. There should be a new replace-form log and a new update-name log.

💭 Notes

Several things in this PR

1. Pass ip address and source details from ImportTaskView to the task
2. Update ImportTask._run_task to record details about the asset being updated in the messages field
3. Update import_in_background to return the uid of the task, which will be sent as result in the task_success signal
4. Add a signal receiver for task_success that fetches the ImportTask from the uid and calls a new method in ProjectHistoryLog to create a log (or several) from it
5. Add a new method in ProjectHistoryLog that creates a replace-form log and possibly an update-name log if the name was changed by the import
6. Extra change: add log_subtype to the fields validated in _check_common_metadata
7. Extra change: change the questions in the asset_with_settings_and_qa fixture to make it easier to distinguish from other assets

The unit tests are a little redundant, but they are meant to check slightly different things. The ones in test_project_history_logs test the whole flow. The ones in test_models test that we know how to make logs from import tasks after they run. The ones in test_api_imports check that the import tasks are storing the correct information.
