Description of problem:
When exporting complete library content (hammer content-export complete library), an auxiliary CV "Export-Library" is created, backed by auxiliary katello repositories (with pulp_id like 1-Export-Library-Library-25807266-9eb3-4361-ab75-c9a928083c6f and relative_path like RedHat/Library/Export-Library/custom/ZOO_Product/ZOO-repo).

(Only?) When Library LE is assigned to a Capsule, these auxiliary repos are synchronized there, redundantly. Moreover, in some scenario I am unable to reproduce ATM, presence of these repos on Capsule can block package download from Sat to Caps, since:
- the pulpcore Repo objects on the Capsule are created along with Remotee objects with some weird certs (this bit I cant reproduce but saw it at a customer)
- assuming the Capsule has On Demand download policy set and a client wants to fetch a package from Capsule that is not present, the Capsule choses among *all* repos that has the RPM associated
- from that list of repos, it *can* chose the 1-Export-Library repo, with wrong certs
- so then Capsule requests Satellite to fetch packages with invalid certs, which fails on "[SSLCertVerificationError: (1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1131)')]" error
- when this happens, it is SUPER confusing and difficult to understand the core issue (ridiculous & offending repo on Capsule)


Please prevent synchronizing the auxiliary repos to Capsules.


Version-Release number of selected component (if applicable):
Sat 6.11 or newer


How reproducible:
100%


Steps to Reproduce:
1. Have some (smaller) repos with Immediate download policy synced to Satellite
2. Run "hammer content-export complete library" to pretend ISS
3. Have Capsule associated with Library LE
4. Sync that Capsule
5. Check the Capsule has also the 1-Export-Library repos synced and available to consumers:

(in pulpcore psql - in my example, I had 2 repos with Immediate download policy, both appears in the ISS export *and* also on Caps):

pulpcore=# SELECT pulp_id,name FROM core_repository WHERE name LIKE '%Export-Library%';
               pulp_id                |                             name

               pulp_id                |                             name                              |                                    base_path

(2 rows)

pulpcore=# 

6. Check the same on Satellite - there wont be any pulp repo (while distribution will be there, just for the sake of data export)


Actual results:
5. shows repos synced to the Capsule, while they are not present on Satellite.


MOREOVER (this deserves a new bug?): registering a client directly via sub-man, I can chose Library/Export-Library Environment - is that expected? Like:

# subscription-manager register --username=admin --password=nereknu
Registering to: pmoravec-caps612.satotest.redhat.com:443/rhsm
Hint: User "admin" is member of following organizations: RedHat, test_org
Organization: RedHat 
Hint: Organization "RedHat" contains following environments: Library, Library/cv_rhel8, DEV/cv_rhel8, Library/Export-Library   ## <<<--- is this OK?
Environment: Library/Export-Library 
The system has been registered with ID: f09c7f1f-1236-403c-9909-316666ca9893
..


Expected results:
5. Caps should not get the Export-Library repos synced

(can a client get offered the Library/Export-Library Environment..? I really dont know..)


Additional info:
ibalou++ and partha++ for hints:

1)
product.repositories.has_url.library.with_type(acs.content_type)

I think we need to change this to:

product.repositories.has_url.library.in_default_view.with_type(acs.content_type)

2) Caps sync repos to ignore shall be modified accordingly at https://github.com/Katello/katello/blob/master/app/models/katello/content_view.rb#L98 ?
