* Expose some of session's storage as public, as well as set_keys
Seemingly there's no reason not to do this, as anyone can always do
it the "hard way" by constructing storage keys or extrinsics.
* Use trait to expose `is_registered` function
* Missed removing a pub keyword
* Move trait to support, add docstrings
* Adding script for rename, could be applicable for nodes on top of it, too
* add stderr and gitlab ci features
* apply script
* fix now minor details in expected stderr
* Update the Cargo.lock
* fix name: sc-transaction -> sc-tracing
* fix rename in script, too
