SSL issue by an upload with xloader

Hi!

I am using CKAN 2.9.4 with ckanext-xloader.0.8.0. I have a productive CKAN instance with https.
I set ckanext.xloader.ssl_verify to False but I still get an SSLError when I try to upload a csv file:

```
Traceback (most recent call last):
File "/usr/lib/ckan/datapusher/lib/python3.8/site-packages/apscheduler/scheduler.py", line 512, in _run_job
retval = job.func(*job.args, **job.kwargs)

resource = get_resource(resource_id, ckan_url, api_key)

r = requests.post(url,

r = adapter.send(request, **kwargs)
File "/usr/lib/ckan/datapusher/lib/python3.8/site-packages/requests/adapters.py", line 514, in send
raise SSLError(e, request=request)
requests.exceptions.SSLError: HTTPSConnectionPool(host='myckan.com', port=443): Max retries exceeded with url: /api/3/action/resource_show (Caused by SSLError(SSLEOFError(8, 'EOF occurred in violation of protocol (_ssl.c:1131)')))
```

What could be wrong here?

Best regards

Start with datapusher/jobs.py at get_resource and the requests.post call shown in the traceback, then trace how ckanext.xloader.ssl_verify is passed into the upload path. Reproduce the CSV upload with the stated CKAN 2.9.4 and xloader 0.8.0 configuration; done means identifying why the SSL setting is not applied or documenting the missing configuration needed to avoid the error.
