* Remove footgun around session keys/handlers - `OpaqueKeys` now has an associated type `KeyTypeIdProviders`. This can be used in the runtime as input for `SessionHandler` from the session trait. - `impl_opaque_keys` now works with modules and extracts the `KeyTypeId` from the module directly. - Added some checks to the `session` storage initialization that checks that the `SessionHandler` and `Keys` use the same number of keys and that the order is equal. * Update core/sr-primitives/src/traits.rs
