Need ability to disable sync for single repository instead of entire product
Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1223056
Description of problem:
Products are automatically generated with many sub repositories. Sync schedules should be set on a per repo basis so some content could be synced less often or only manually.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. open a product with a sync schedule and view the repos for that product
2. change the sync schedule on that repo on the details tab
3. change reflect the entire product, not just that repo
Sync schedule is for the product not each repo
individual repos should be allowed to have different sync schedules.
