   ## What is the best way to verify this PR? Please include manual steps or automated tests. 
   ### (If no tests are part of this PR, please provide explanation as to why no tests are included.)
   
   Using TP create (or modify) an active DS with Edge Header Rewrite Rule like the following, with appropriate __RETURN__ keywoards embedded:
   
   ```
   cond %{SEND_RESPONSE_HDR_HOOK}
   set-header Access-Control-Allow-Origin *
   cond %{SEND_RESPONSE_HDR_HOOK}
   set-header Content-Type "plain/text" [L]
   ```
   
   Queue the appopriate CDN and pull the new config via traffic_ops_ort.pl syncds.  Verify the hdr_rw_<ds>.config has the above contents.
   
   Remove one of the  
   cond %{SEND_RESPONSE_HDR_HOOK}
   lines, update and Queue.
   
   Repeat with reordering the rules.
   
   I also ran tests with the current ORT to verify that it incorrectly did not detect changes for these conditions.
