authorize_upgrade: TxDescriptor<{
    check_version: boolean;
    code_hash: FixedSizeBinary<32>;
}>

Authorize an upgrade to a given code_hash for the runtime. The runtime can be supplied later.

The check_version parameter sets a boolean flag for whether or not the runtime's spec version and name should be verified on upgrade. Since the authorization only has a hash, it cannot actually perform the verification.

This call requires Root origin.
