[RFE] add confirmation step for manifest deletion (explaining when refresh will do, and when have to use delete)
Cloned from BZ:
Description of problem:
It's reported that oftentimes customers delete manifest when trying to update subscriptions / upload a newer manifest, in which case all that's needed is a Refresh, and deletion would cause problems by losing/disconfiguring server and client subscriptions etc. The only times where manifest needs to be deleted includes when a Satellite server is no longer active or the manifest has been removed from the Customer Portal.
A confirmation step will address this confusion by explaining to users refresh vs delete and asking if they're sure they want to delete manifest or just go back and refresh it.
