manage.py import should provide some kind of progress feedback

Right now we do not know what happens and what was done.
Design TBD

I added progress bar in NVD importer . Using tqdm package

[AmitGupta7580]

As you know data is importing in 2 different processes.

1. Downloading data from resources and cast into Advisory class.
2. Adding advisory to postgresql database.

Some importers do these task at same time e.g : NVD
While other importers first collect all the data then save it to database e.g : archlinux

[Solution] According to me To add a common progress bar first we has to implement all importers in similar fashion.

Eventually we want to move to non-batch proccessing

I think this can be better done after #338

Hi! I was looking this issue#318 and was wondering if it is still open or if it has already been resolved. If it's still open, I'd be happy to work on it. Please let me know. Thank you!
