Scripted test to upload a file and check it is imported

When developing AirCan i want a scripted test I can run to test the end to end functioning of a load of data into DataStore

Acceptance

[ ] Create a dataset in CKAN test instance
[ ] Create resource with a file
[ ] Check on status of run using {ckan instance}/api/3/aircan_status
[ ] Check datastore is updated (called data API): ... /api/3/datastore_search ...

[ ] Research what already exists (is it useful) @cuducos
- [ ] Review Integration tests in ckanext-aircan https://github.com/datopian/ckanext-aircan/tree/master/cypress NOTES from eduardo: most of the tests might be repeated (comparing to integration-tests repo), maybe just focus on https://github.com/datopian/ckanext-aircan/blob/master/cypress/integration/aircan-connector.js
- [ ] Review Integration tests for reference
[x] Decide whether you are running against a local instance or the cloud? If cloud what instance in the cloud? Let's run against the cloud and use the enterprise (+ versioning) https://ckan-enterprise-versioning.dev.datopian.com instance. As soon as we have an enterprise+aircan instance up and running we will use that!
[ ] Test steps (in cypress) - we can use ckan-client-js ...
- [ ] Create a dataset in CKAN test instance @cuducos
- [ ] Create resource with a file @cuducos
- [ ] Check you can download the file @cuducos
- [ ] ~~Check on status of run using {ckan instance}/api/3/aircan_status~~ but we don't know run_id so how do we get it? => Maybe skip this
- [ ] Check datastore is updated (called data API): call ... /api/3/datastore_search?resource_id={RES_ID} ... BLOCKED until we have instance deployed with AirCan
[ ] Test steps 2
- [ ] Explicitly submit dag by calling aircan_submit
- [ ] Check on aircan_status using return run_id
- [x] Rename dag_status to aircan_status https://github.com/datopian/ckanext-aircan/issues/27
