…errors Backport #40571 to branch/v15 This commit modifies OpaqueAccessDenied to return an identical generic NotFound error whether the input error is NotFound or AccessDenied. The commit also updates all call sites of OpaqueAccessDenied to use it in the paths where there is any error fetching the resource as well as when access is denied. It doesn't do much good to return AccessDenied errors as NotFound, if they don't match the NotFound error you would get if the resource really didn't exist. It's trivial to tell the errors apart and discover the existence of a resource you shouldn't be allowed to access. The commit attempts to mitigate that issue and properly hide the existence of resources the user should not be allowed to list. Changelog: generic "not found" errors are returned whether a remote cluster can't be found or access is denied. --------- Co-authored-by: rosstimothy <39066650+rosstimothy@users.noreply.github.com>
