Disabling feature for cluster repositories

[momesgin]

Summary

Fixes #12485

Occurred changes and/or fixed issues

Changes on the Repositories page:

• New action item for disabling/enabling is added to the menu and the bulkable action buttons
• A disabled state is displayed when a repo is disabled, no changes for enabled state
• Refresh action gets removed from the action items when a repo is disabled

Changes on the Charts page:

• The disabled repository is removed from the dropdown list

Changes on the Installed Apps page:

• Since the disabled repos are now filtered from the list of the repos, no available versions will be checked from the disabled repos in order to recommend for an update

Technical notes summary

The main change is filtering the disabled repos on the store level.

Areas or cases that should be tested

E2E tests are added to test this change on Repositories and Charts pages, but a manual test is needed to cover the upgrade case on the Installed Apps page.

Areas which could experience regressions

Shouldn't cause any regressions, hopefully.
