Retrieving all items from the database takes some time.
The task is thus handled by the RQ worker.
We use ajax to periodically monitor the status of the job

A progress bar is displayed to let the user see the progress.

The mechanism put in place could be re-used for other use cases.

JIRA INFRA-545 #action In Progress

Allow to use a scanner configured as keyboard to register items

1. The attributes should be selected manually
2. Focus set manually on ICS id
3. Scan an ICS id -> prefix removed and focus set to serial number
4. Scan serial number
5. Click on submit
6. Focus set automatically on ICS id
7. Repeat from 3

Sorting on manufacturer/model/location/status requires
a join which removes the row with empty field.
Disable it until we find a way to sort properly including null values.

When there are more than a 1000 items in the table, retrieving and
displaying all items takes about 7 seconds.
This is every time we refresh the items page, which is too slow.

Column not visible but searchable.
Allow to search comments and TAG number for items imported from JIRA.
