D6503: statecheck: added support for STATES

[pulkit (Pulkit Goyal)]

pulkit added a comment.


  This patch does multiple things,
  
  1. improve how states are registered
  2. move STATES to cmdutil
  
  it will be nice if we take 1) out and amend that into the initial patch which introduced how states are registered.
