mod_admin_shell: Refactor 'cert' column Removes some dead code and hopefully simplifies a bit. There's a tree of possibilities with the two tri-state status properties, something like chain: * nil -- cert validation disabled? * invalid -- something wrong with the chain (including ee cert) * valid -- chain ok cert: * nil -- incomplete validation?? * invalid -- mismatched names or such * valid -- all good!
