REVISION SUMMARY
  In order to have fractional scaling in kwin, we need to communicate it with 
  kscreen, which means changing the data type in our config protocols.
  
  This introduces a new method on outputdevice and outputconfiguration
  to set/request scale as a float.
  
  wl_output is and should remain unchanged as an int
  
  No urgent rush for reviewing/merging this as it's useless without other changes.

TEST PLAN
  Attached unit tests
