Sync Status - Select All selects non-visible repositories for syncing
Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1171140
Description of problem:
I intended on syncing a single product in Satellite 6 by expanding only a single product and pressing "select all". Satellite 6 then synced every repository since select all selects every repository on the page rather than everything that is visible to the user. This can mis-lead a user to believe they have selected only the products they have expanded. In my case instead of syncing 7GiB of content, I synced 56GiB of content.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Navigate to Sync Status Page
2. Expand one Product, press select all
3. Expand other products and note how repositories are checked for syncing although they were not visible to the user.
Select all selects repositories that are not necessarily visible to the end user since the products may not have been expanded.
As a User, I'd expect only the visible repositories to be selected and then synced when I press "Synchronize Now"
A per-product select all would avoid confusion and unintentional syncing (or re-syncing) of content by a Satellite 6 user.
