Cleanup + Bug fixes

[SanjalKatiyar]

https://issues.redhat.com/browse/RHSTOR-6568

Fixes for:

• Try to navigate to buckets list page Route (by specifically typing in the URL) when deployed in "Full deployment" mode - Route works for MCG standalone, but page breaks for other modes, page should not break, even if other modes are not supported.
• S3 commands and their types under shared should be defined in alphabetical order.
• Add favourites option to the bucket overview header.
• Add object/bucket count in the list page pagination, eg: "1 - 300 of many".
• Add file/folder icons to objects list.
• Pagination not working correctly.
