   ## What changes were proposed in this pull request?
   
   Currently, Knox masks all connection errors as 500 errors, when they may be more accurately described using other error codes, especially 504. A change has been made to display a 504 error in the event of a socket timeout..
   
   (Please fill in changes proposed in this fix)
   
   ## How was this patch tested?
   
   Ran ant verify under Knox 1.2.0. The patch was generated against the Knox 1.2.0 branch, and subsequently applied to Knox 1.4.0. Currently ant verify is failing, but these are most likely transient errors as the same errors appear in master. Still running tests.
   
   (Please explain how this patch was tested. For instance: running automated unit/integration tests, manual tests. Please write down your test steps as detailed as possible)
   (If this patch involves UI changes, please attach a screen-shot; otherwise, remove this)
