Deprecate Authorize class and any_auth function

The Authorize class in salt.auth is not used in Salt code any where and
is dead code. This puts a deprecation path on the class.

The salt.utils.minions.CkMinions.any_auth functions is also marked for
deprecation. This function is only called by the "rights_check" function
in the Authorize class.

Since the Authorize class will be removed in Salt Neon, then the any_auth
function should be removed in Neon as well.
