Title: [pharmacy] Remove low stock point and use alert_level everywhere

Summary:
Having low_stock_point and alert_level is too confusing. I've picked alert_level
since both alert_level and quantitiy are floats, whereas low_stock_point was an
integer.

In making these modifications, the low_stock_alerts feature now passes.

Test Plan:
```sh
$ cucumber features/pharmacy_low_stock_alerts.feature
```

Revert Plan:
Reverse the migration.
