    * grandpa: Write Grandpa authorities to well known key.
    
    Instead of requiring execution proofs for Grandpa authorities, this
    enables much simpler storage proofs.
    
    * grandpa: Introduce named AuthorityList type.
    
    * grandpa: Storage migration for srml-grandpa module.
    
    * Remove no-longer-used GrandpaApi runtime API.
    
    * grandpa: Write AuthorityList to storage with encoding version.
    
    We expect the AuthorityList type may change (eg. key changes). To make
    upgrades smoother, include a version in the stored value.
    
    * Bump node runtime spec version.
    
    * Update srml/grandpa/src/lib.rs
