Content > Red Hat Subscriptions landing page/endpoint is not uniform
Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1225923
Description of problem:
Sometimes when user navigates to Content > Red Hat Subscriptions, they are taken to
... but other times when navigating, via the UI, to the same location, they are taken/redirected to
Version-Release number of selected component (if applicable):
I have one reproducible case but I am not sure it is the best
Steps to Reproduce:
1. Install satellite. Navigate to Content > Lifecycle Environments (or nearly anywhere else in the UI) and then to Content > Red Hat Subscriptions
2. Observe user is taken to /subscriptions/manifest/import endpoint
3. From within the Subscriptions page itself (and perhaps other pages?) nav to Content > Red Hat Subscriptions
4. Observe results.
Depending where you are or in certain circumstances (heuristic not completely known though as noted we have a repro case here), "Content > Red Hat Subscriptions" takes user to one of two different endpoints.
Content > Red Hat Subscriptions always take user to same page/endpoint.
Such behavior is confusing and will lead to support calls with people wondering what is going on. I am willing to remove blocker if:
(a) the heuristic is fully determined and
(b) found to be limited to navigating to "Content > Red Hat Subscriptions" from within the Manage/Import Manifests page itself, and
(b) This is doc'd.
Fixes #10721: Redirect to manifest import consistently if no subscriptions.
