Feature Description

Introduces breaking changes to the Core runtime API by letting Core::initialize_block return an enum:

fn initialize_block(header: &<Block as BlockT>::Header)
+  -> ExtrinsicInclusionMode;

enum ExtrinsicInclusionMode {
  /// All extrinsics are allowed in this block.
  AllExtrinsics,
  /// Only inherents are allowed in this block.
  OnlyInherents,
}
