Subscription update value of 0 passes UI validation, but fails in task.
Description of problem:
Entering a value of 0, in the entitlements field, passes the UI validation. However, the task itself will fail with "Quantity value must be greater than 0".
See attached screenshot
Version-Release number of selected component (if applicable):
6.4 Snap 9
Steps to Reproduce:
1. Upload a manifest with subscriptions.
2. Navigate to the Subscriptions page
3. Edit an entitlements field, and enter a value of 0
There are no validation warnings, and you can submit changes.
Validation checks catch the bad value and does not let you submit changes.
